FIELD OF THE INVENTION

The invention relates to a transgenic Glycine max (soybean) eventreferred to as MON87751. The event provides two different modes ofaction of resistance from lepidopteran infestations of soybean byproviding a unique combination of insecticidal toxin proteins notpreviously available in soybean plants. The combination of theseinsecticidal toxin proteins is highly efficacious for controllinglepidopteran species infestations characteristic to soybean plants. Theinvention also relates to soybean plants, plant parts, plant seeds,plant cells, progeny plants, agricultural products, and methods relatedto event MON87751, and provides nucleotide molecules that are unique tothe event, created in connection with the insertion of transgenic DNAinto the genome of a Glycine max (soybean) cell, and useful fordetecting the presence of this event in biological samples containingsoybean nucleic acids.

BACKGROUND OF THE INVENTION

Soybean (Glycine max) is an important crop in many areas of the world,and biotechnology methods have been applied to this crop in order toproduce soybean varieties with desirable traits. One such desirabletrait is insect resistance. The expression of an insect resistancetransgene in a plant can confer the desirable trait of insect resistanceon the plant, but expression of the transgene may be influenced by manydifferent factors including the orientation and composition of thecassettes driving expression of the individual genes transferred to theplant chromosome, the chromosomal location, and the genomic result ofthe transgene insertion. For example, it has been observed in plantsthat there is variation in the level and pattern of transgene expressionamong individual events that differ in the chromosomal insertion site ofthe transgene but are otherwise identical. There are also undesirableand/or desirable phenotypic or agronomic differences between events.Therefore, it is often necessary to produce and analyze a large numberof individual plant cell transformation events in order to select anevent having both the desirable trait and the optimal phenotypic andagricultural characteristics suitable for commercial success. Selectingthe preferred transgenic event requires extensive molecularcharacterization, as well as greenhouse and field trials with manyevents over multiple years, in multiple locations, and under a varietyof conditions. A significant amount of efficacy, phenotypic, andmolecular data is collected, and the resulting data and observations arethen analyzed by teams of scientists and agronomists with the goal ofselecting one or more commercially suitable events. Such an event, onceselected, is then used for introgression of the desirable transgenictrait into other genetic backgrounds using plant breeding methods, thusproducing a number of different crop varieties that contain thedesirable trait and are suitably adapted to specific local agronomicconditions.

Transgenic soybeans which rely upon expression of a single toxin forinsecticidal control of insect infestation may be at risk of limiteddurability because of the increased likelihood of development ofresistance to the toxin by the insect pests. Similarly, transgenicsoybeans containing toxic agents that do not provide multiple uniquemodes of action could also be at risk of limited durability. The firstavailable soybean that produces a protein toxic to lepidopteranscontains a single toxin protein, Cry1Ac. A recent soybean transgenicevent has been disclosed that contains Cry1Ac and Cry1F toxin proteins.If resistance to Cry1Ac occurs, the Cry1Ac and Cry1F transgenic eventwould be left with only the Cry1F toxin as its source of efficacy. It istherefore necessary to provide for a soybean plant that has two or moretoxic agents that control the pests controlled by Cry1Ac in which noneof the toxic agents bind the same or substantially the same receptors inthe target insect midgut that are bound by Cry1Ac. The inventiondescribed herein provides for a transgenic soybean event MON87751 thatovercomes the durability problem described above for the soybeantransgenic events described in the prior art, by providing two or moreagents toxic to lepidopteran pest species, in which neither toxic agenthas previously been included in any soybean plant for the purpose oftargeting for control the lepidopteran pests of soybean.

To make a transgenic plant containing a single transformation event, aportion of a recombinant DNA construct is transferred into the genome ofa soybean cell, and the soybean cell is subsequently grown into a plant.A soybean cell into which the event is initially transferred isregenerated to produce the R0 generation. The R0 plant and progenyplants from the R0 plant can be tested for any desired trait(s), but theeffectiveness of the event can be impacted by cis and/or trans factorsrelative to the integration site in the transformation event. Thephenotype conferred by the event can also be impacted by the size anddesign of the DNA construct, which can vary by the combination ofgenetic elements in an expression cassette, number of transgenes, numberof expression cassettes, and configuration of such elements and suchcassettes. Identifying an event with desirable traits can be furthercomplicated by factors such as plant developmental, diurnal, temporal,or spatial patterns of transgene expression; or by extrinsic factors,e.g., environmental plant growth conditions, water availability,nitrogen availability, heat, or stress. Thus, the ability to obtain anevent conferring a desirable set of phenotypic traits is not readilypredictable.

SUMMARY OF THE INVENTION

The invention provides transgenic soybean plants comprising eventMON87751 exhibiting superior properties and performance compared toexisting transgenic soybean plants and to new events constructed inparallel. The soybean event MON87751 contains, at a single locus ofinsertion in the soybean genome, two linked expression cassettes whichindependently confer the trait of resistance to lepidopteran insectpests. Combined the two linked expression cassettes in soybean eventMON87751 provide two modes of action against insect pest species in theorder Lepidoptera, including Chrysodeixis spp., Spodoptera spp.,Helicoverpa spp., Crocidosema spp., Rachiplusia spp., Anticarsia spp.,Elasmopalpus spp., and Plathypena spp. The dual modes of action provideredundancy of insecticidal control against lepidopteran pest species,and significantly reduces the likelihood of the development ofresistance to the pest control traits.

The event MON87751 is characterized by specific unique DNA segments thatare useful in detecting the presence of the event in a sample. A sampleis intended to refer to a composition that is either substantially puresoybean DNA or a composition that contains soybean DNA. In either case,the sample is a biological sample, i.e., it contains biologicalmaterials, including but not limited to DNA obtained or derived from,either directly or indirectly, from the genome of soybean comprisingevent MON87751. “Directly” refers to the ability of the skilled artisanto directly obtain DNA from the soybean genome by fracturing soybeancells (or by obtaining samples of soybean that contain fractured soybeancells) and exposing the genomic DNA for the purposes of detection.“Indirectly” refers to the ability of the skilled artisan to obtain thetarget or specific reference DNA, i.e. a novel and unique junctionsegment described herein as being diagnostic for the presence of theevent MON87751 in a particular sample, by means other than by direct viafracturing of soybean cells or obtaining a sample of soybean thatcontains fractured soybean cells. Such indirect means include, but arenot limited to, amplification of a DNA segment that contains the DNAsequence targeted by a particular probe designed to bind withspecificity to the target sequence, or amplification of a DNA segmentthat can be measured and characterized, i.e. measured by separation fromother segments of DNA through some efficient matrix such as an agaroseor acrylamide gel or the like, or characterized by direct sequenceanalysis of the amplicon or cloning of the amplicon into a vector anddirect sequencing of the inserted amplicon present within such vector.Alternatively, a segment of DNA corresponding to the position within thesoybean chromosome at which the transgenic DNA was inserted into thesoybean chromosome and which can be used to define the event MON87751,can be cloned by various means and then identified and characterized forits presence in a particular sample or in a particular soybean genome.Such DNA segments are referred to as junction segments or sequences, andcan be any length of inserted DNA and adjacent (flanking) soybeanchromosome DNA so long as the point of joining between the inserted DNAand the soybean genome is included in the segment. SEQ ID NO:1, SEQ IDNO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7,SEQ ID NO:8, and SEQ ID NO:10 and the reverse complement of each ofthese, are representative of such segments.

The specific sequences identified herein may be present uniquely inevent MON87751, or the construct comprised therein, and theidentification of these sequences, whether by direct sequence analysis,by detecting probes bound to such sequences, or by observing the sizeand perhaps the composition of particular amplicons described herein,when present in a particular soybean germplasm or genome and/or presentin a particular biological sample containing soybean DNA, are diagnosticfor the presence of the event MON87751, or the construct comprisedtherein, in such sample. It is known that the flanking genomic segments(i.e., the soybean genome segments of DNA sequence adjacent to theinserted transgenic DNA) are subject to slight variability and as such,the limitation of at least 99% or greater identity is with reference tosuch anomalies or polymorphisms from soybean genome to soybean genome.Nucleotide segments that are completely complementary across theirlength in comparison to the particular diagnostic sequences referencedherein are intended to be within the scope of the present invention.

The position of the nucleotide segments of the present inventionrelative to each other and within the soybean genome are illustrated inFIG. 1 and the nucleotide sequence of each is illustrated as set forthin SEQ ID NO:10. Nucleotide segments that characterize the eventMON87751 and which are diagnostic for the presence of event MON87751, orthe construct comprised therein, in a sample include SEQ ID NO:1, SEQ IDNO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7,SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, SEQ ID NO:17, SEQ ID NO:18, SEQID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ IDNO:24, SEQ ID NO:25, or SEQ ID NO:26. The presence of one, or two, ormore of these nucleotide sequences in a sample, when such samplecontains soybean tissue and thus soybean DNA, are diagnostic for thepresence of the event MON87751, or the construct comprised therein.

It is intended by use of the word “derived”, that a particular DNAmolecule is in the soybean plant genome, or is capable of being detectedin soybean plant DNA. “Capable of being detected” refers to the abilityof a particular DNA segment to be amplified and its size and or sequencecharacterized or elucidated by DNA sequence analysis, and can also referto the ability of a probe to bind specifically to the particular DNAsegment, i.e. the target DNA segment, and the subsequent ability todetect the binding of the probe to the target. The particular DNAsegment or target DNA segment of the present invention is present withinsoybean that contains the insertion event MON87751.

By reference to soybean it is intended that soybean cells, soybean seed,soybean plant parts and soybean plants are within the scope of thepresent invention so long as each embodiment contains a detectableamount of DNA corresponding to any one, two, or more of the segmentsthat are described herein as being diagnostic for the presence of thesoybean event MON87751 DNA. Soybean plant parts include cells; pollen;ovules; flowers; pods; seed; root tissue; stem tissue; and leaf tissue.Commodity products that are made from soybean in which a detectableamount of the segments of DNA described herein as being diagnostic forthe presence of the event MON87751 are within the scope of theinvention. Such commodity products may include whole or processedsoybean seed, soybean oil, soybean protein, soybean meal, soybean flour,soybean flakes, soybean bran, soybean milk, soybean cheese, soybeanwine, animal feed comprising soybean, paper comprising soybean, creamcomprising soybean, soybean biomass, and fuel products produced usingsoybean plants and soybean plant parts.

The DNA of soybean event MON87751 may be present in each cell and ineach genome on one chromosome of the soybean plant, soybean seed, andsoybean tissues containing the event. As the soybean genome istransmitted to progeny in Mendelian fashion, if a soybean plant werehomozygous for the event MON87751 insertion, each progeny soybean plantand cell would contain the event DNA on each allele of the parentalchromosome containing the event MON87751 insertion and inherited by theprogeny from the parent(s). However, if the soybean genome containingthe event MON87751 DNA is a heterozygous or hybrid parent, then aboutfifty percent of the pollen and about fifty percent of the ovulesengaged in mating from hybrid parents will contain the soybean eventMON87751 DNA, resulting in a mixed population of progeny that containthe event MON87751 DNA, and the percentage of such progeny arising fromsuch crosses with hybrids can range anywhere from about fifty to aboutseventy five percent having the event MON87751 DNA transmitted to suchprogeny.

The DNA molecules of the present invention may be unique to the twoseparate junctions on either end of the inserted transgenic eventMON87751 DNA and the soybean genome DNA that is adjacent to, i.e.flanking, each end of the MON87751 inserted DNA, or unique to thesoybean event MON87751 inserted DNA. These molecules, when present in aparticular sample analyzed by the methods described herein using theprobes, primers and in some cases using DNA sequence analysis, may bediagnostic for the presence of an amount of event MON87751 soybean inthat sample. Such DNA molecules unique to the soybean event MON87751 DNAcan be identified and characterized in a number of ways, including byuse of probe nucleic acid molecules designed to bind specifically to theunique DNA molecules followed by detection of the binding of such probesto the unique DNA, and by thermal amplification methods that use atleast two different DNA molecules that act as probes but the sequence ofsuch molecules may be somewhat less specific than the probes describedabove. The skilled artisan understands that contacting a particulartarget DNA with a probe or primer under appropriate hybridizationconditions will result in the binding of the probe or primer to thetargeted DNA segment.

The DNA molecules of the present invention may be target segments of DNAthat may be capable of amplification and, when detected as one or moreamplicons of the represented length obtained by amplification methods ofa particular sample, may be diagnostic for the presence of eventMON87751, or the construct comprised therein, in such sample. Such DNAmolecules or polynucleotide segments may have the nucleotide sequencesas set forth in each of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ IDNO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9,SEQ ID NO:10, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20,SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25,and SEQ ID NO:26, and are further defined herein and in the examplesbelow. Primer molecules and/or probes may be provided in kit form alongwith the necessary reagents, including controls, and packaged togetherwith instructions for use.

Recombinant DNA molecules of the present invention may be present withinor derived from a microorganism. A microorganism is intended to includeany microscopic cell, whether prokaryote or eukaryote or otherwise thatcontains DNA within a genome or chromosome or an extra-chromosomal DNAstructure more commonly referred to as a plasmid or vector. In oneembodiment, microscopic organisms may include bacteria (prokaryotes) andcells corresponding to higher life forms (eukaryotes) which are beneaththe visual range of the average human, typically beneath fifty cubicmicrons and more generally beneath ten cubic microns. Bacteria arecommon microscopic microorganisms that may contain a vector or plasmidthat contains one or more or all of the novel DNA segments of thepresent invention, including each of the respective expression cassettespresent as set forth in SEQ ID NO:9. Plant cells and particularlysoybean plant cells of the present invention may contain any one, two,or more or all of the novel DNA segments of the present invention.

Probes for use herein may comprise DNA molecules or polynucleotidesegments of sufficient length to function under stringent hybridizationconditions as defined herein to bind with a particular target DNAsegment, i.e., a unique segment of DNA present within and diagnostic forthe presence of, event MON87751 DNA in a sample. Such a probe can bedesigned to bind only to a single junction or other novel sequencepresent only in the soybean event MON87751 DNA, or to two or more suchsingle junction segments. The detection of the binding of such a probeto a DNA molecule in a particular sample suspected of containing soybeanDNA is diagnostic for the presence of soybean event MON87751 in thesample.

Primers may comprise pairs of different oligonucleotides orpolynucleotide segments for use in a thermal amplification reactionwhich amplifies a particular DNA target segment. Each primer in the pairis designed to bind to a rather specific segment of DNA within or nearto a segment of DNA of interest for amplification. The primers bind insuch way that these then act as localized regions of nucleic acidsequence polymerization resulting in the production of one or moreamplicons (amplified target segments of DNA). In the present invention,use of primers designed to bind to unique segments of soybean eventMON87751 DNA in a particular biological sample and that amplifyparticular amplicons containing one or more of the junction segmentsdescribed herein, and the detection and/or characterization of suchamplicons upon completion or termination of the polymerase reaction, isdiagnostic for the presence of the soybean event MON87751 in theparticular sample. The skilled artisan is well familiar with thisamplification method and no recitation of the specifics of amplificationis necessary here.

Soybean plants, soybean plant cells, soybean plant tissues and soybeanseed of the present invention may be resistant to infestation bylepidopteran insect pests, including but not limited to Chrysodeixisspp., Spodoptera spp., Helicoverpa spp., Crocidosema spp., Rachiplusiaspp., Anticarsia spp., Elasmopalpus spp., and Plathypena spp. Theresistance to infestation by lepidopteran species arises in connectionwith the expression of two different DNA segments, encoding twodifferent insecticidal proteins, that are operably and covalently linkedwithin the inserted transgenic DNA: a Cry2Ab protein expressed from theexpression cassette at the 5′ proximal end of the inserted transgenicDNA as set forth in SEQ ID NO:10 and illustrated in FIG. 2; and aCry1A.105 protein expressed from the expression cassette at the 3′ endof the inserted transgenic DNA as set forth in SEQ ID NO:10 andillustrated in FIG. 2. The Cry2Ab protein is expressed from an At.Act2promoter, while the Cry1A.105 protein is expressed from an At.RbcS4promoter. The Cry2Ab and the Cry1A.105 proteins are agents toxic tolepidopteran insect pest species.

The construct used to generate soybean event MON87751 has the promotersdriving expression of the Cry2Ab and the Cry1A.105 proteins positionedin a relative tandem orientation of transcription so that expressionfrom each promoter of the respective Cry proteins proceeds in the samedirection, but each from their separate respective promoters (see FIG.2). Other constructs which were evaluated varied in the combination ofthe use of expression elements, i.e., enhancer (E), promoter (P), leader(L), introns (I), chloroplast targeting peptide (CTP), and 3′UTR (T).Also, the constructs contained either a vector stack of both Cryproteins (Cry2Ab and Cry1A.105), or contained a single Cry protein,i.e., Cry2Ab or Cry1A.105. A further variation in the expressionconstructs was the relative orientation of the two cassettes for the Cryproteins in the vector stack constructs. Specifically, the two cassetteswere either in a tandem orientation of transcription, or the twocassettes were in a divergent orientation so that expression from eachpromoter of the two Cry proteins is away from a point centered betweenthe two promoters, i.e., transcription of each expression cassetteproceeds in opposite directions and does not converge. The DNA sequenceencoding Cry1A.105 was sequence diversified in some constructs relativeto the sequence in the transgene inserted into event MON87751. Finally,in two of the constructs with the two Cry expression cassettes orientedin reverse orientation of transcription, transcription enhancers werepositioned between the diverging promoters (see FIG. 2).

The event MON87751 was selected based on comparisons to thousands ofdifferent independent transgenic events each transformed with one of theconstructs containing a T-DNA segment as illustrated in FIG. 2, and toeither event MON87701 and/or to event GM_A19478 (generated at the sametime as MON87701, and both expressing Cry1Ac); to a transgenic event40-3-2 (conferring tolerance to the herbicide glyphosate); and tonon-transgenic control soybean (A3555, or A5547). The results asillustrated below in the examples show that the event MON87751 exhibitedsuperior properties due to expression of the Cry2Ab and Cry1A.105proteins. The plurality of transgenic events produced using theconstruct used for generating the event MON87751 were each more likelythan other events produced with other constructs to exhibit efficaciouscontrol of lepidopteran insect pests.

Soybean plants and parts thereof including seed, each containing the DNAcorresponding to event MON87751, are within the scope of the presentinvention. Such plants and parts thereof including seed are resistant tolepidopteran infestation. In certain embodiments, such plants and seedinclude hybrids and inbreds, and plants and seed that contain only oneevent MON87751 allele, i.e., a genome characterized as heterozygous withreference to the locus corresponding to the event MON87751 DNA. Suchhybrids may be produced by breeding plants comprising event MON87751with desirable germplasm as part of the commercial variety developmentprocess and other agriculturally desirable properties of soybean.Hybrids may be produced by any number of methods but a preferred methodtakes advantage of a first inbred (homozygous) parent that contains theevent MON87751 specific allele on both chromosomes at the locus at whichthe event MON87751 DNA is inserted, and breeding the first inbredtogether with a second inbred which does not contain the MON87751 DNA.Both parental inbred varieties will have one or more advantageousproperties desirable in the progeny seed, i.e. the hybrid seed, andthese hybrid seed are heterozygous for the event MON87751 allele.

A transgenic property or allele conferring some additional trait to aplant containing the event MON87751 DNA may be desirable. Other suchtransgenic alleles conferring desirable traits may include herbicidetolerance: GTS 40-3-2, MON87708, MON89788, A2704-12, A2704-21, A5547-35,A5547-127, BPS-CV127-9, DP356043, GU262, W62, W98, DAS-44406-6,DAS-68416-4, FG72, BPS-CV127-9, SYHT04R, SYHT0H2, 3560.4.3.5, EE-GM3,pDAB4472-1606, pDAB4468-0416, pDAB8291.45.36, 127, AAD-12; insectresistance: MON87701, DAS-81419-2; increased enhanced oil composition:DP-305423, G94-1, G94-19, G168, OT96-15, MON87705, MON87769; increasedyield: MON 87712, or nitrogen fixation traits, traits modulating the useof water, resistance to fungal infestation, resistance to nematodeinfestation, and the like. A non-transgenic property (e.g., QTL ormaturity group) may also confer a desirable trait and one with skill inthe art would know how to breed soybean to contain such non-transgenictrait and event MON87751 DNA.

The foregoing and other aspects of the invention will become moreapparent from the following detailed description.

DETAILED DESCRIPTION

The inventors have identified a transgenic soybean event MON87751 thatexhibits commercially acceptable resistance to agriculturally importantinsect pests in the order Lepidoptera such as Spodoptera frugiperda(fall armyworm, FAW), Spodoptera eridania (southern armyworm, SAW),Spodoptera exigua (beet armyworm, BAW), Spodoptera ornithogalli(yellowstriped armyworm, YSAW), Crocidosema aporema (bean shoot moth,BSM), Rachiplusia nu (sunflower looper, SFL), Anticarsia gemmatalis(velvetbean caterpillar, VBC), Chrysodeixis includens (soybean looper,SBL), Helicoverpa zea (soybean podworm, SPW), Helicoverpa gelotopeon(South American bollworm), Elasmopalpus lignosellus, (lesser cornstalkborer), Estigmene acrea (saltmarsh caterpillar), and Plathypena scabra(green cloverworm), amongst others. The event provides two differentoperably linked expression cassettes, one encoding Cry2Ab, and the otherencoding Cry1A.105 insecticidal proteins, and provides two differentmodes of action for resistance to soybean from lepidopteraninfestations. Other transgenic soybean events are known in the art, i.e.MON 88701, which expresses a Cry1Ac Bacillus thuringiensis (Bt) toxinprotein (MacRae et al. 2005, Fischhoff & Perlak 1995). MON 88701provides a single mode of action for resistance to major lepidopteraninsect pests of soybean, though efficacy against Spodoptera spp. is notsignificant. It would be preferable to provide transgenic soybeanexpressing two or more different insecticidal proteins exhibitingefficacy to major pests of soybean and including control of Spodopteraspp. The inventors provide at least one solution to this problem in theform of the soybean event MON87751, which combines two covalently linkedexpression cassettes in one locus within the soybean genome, thesecassettes conferring the traits of expanded lepidopteran speciesresistance, and additionally, provides to the soybean cells, soybeantissues, soybean leaves, soybean pods, soybean seed, and soybean plantsmore than one mode of action to prevent or delay development ofresistance among species of Lepidoptera.

The soybean event MON87751 was produced by an Agrobacterium mediatedtransformation process of soybean meristem tissue with the plasmidconstruct 1. This plasmid construct contains two regions, each boundedby Agrobacterium border segments (T-DNA segment). The first T-DNAsegment contains two linked plant expression cassettes, one expressioncassette encoding a selectable marker and one expression cassetteencoding a scorable marker. The second T-DNA segment contains two linkedplant expression cassettes with the regulatory genetic elementsnecessary for expression in soybean plant cells of two differentinsecticidal proteins, Cry2Ab and Cry1A.105. Due to the two T-DNAsegments in the plasmid construct 1, the T-DNA segment containing theselection/scorable marker genes inserted randomly into the soybeangenome and at a site separate from the site of integration of the T-DNAsegment containing the Cry2Ab and Cry1A.105 expression cassettes, thusallowing for segregation of the two T-DNA segments within the genome ofthe transformed soybean plants during the process of selfing and/orbackcrossing, e.g. screening R1 and higher generation of transgenicplants. The transformed soybean cells were regenerated into intactsoybean plants and individual plants were selected from the populationof plants that showed integrity of the second T-DNA segment encoding theCry2Ab and Cry1A.105 proteins. In R1 and subsequent generations, eventswere selected based on integrity of the second T-DNA segment encodingthe Cry2Ab and Cry1A.105 proteins, and on the absence (i.e.,segregation) of the first T-DNA segment encoding the selectable/scorablemarker cassettes, and for plants not containing any plasmid backbonesequence. The expression of the Cry2Ab and Cry1A.105 insecticidal toxicproteins in the cells of the soybean event MON87751 confers resistanceto lepidopteran insect pests when the soybean cells of event MON87751are provided in the diet the insects.

The plasmid DNA inserted into the genome of soybean event MON87751 wascharacterized by detailed molecular analyses. These analyses included:the insert number (number of integration sites within the soybeangenome), the genomic insert location (the specific site in the soybeangenome where the insertion occurred), the copy number (the number ofcopies of the T-DNA within one locus), and the integrity of thetransgenic inserted DNA. The plasmid construct containing the two linkedexpression cassettes inserted into the soybean genome giving rise to theevent MON87751 contains multiple segments (junction sequences betweenelements used to build or construct the several expression cassettes)that are not known to appear naturally in the soybean genome nor inother vectors or transgenic events of soybean or otherwise (for example,sequences as set forth in SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ IDNO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9,SEQ ID NO:10, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20,SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25,and SEQ ID NO:26). In addition, the transformation event that gave riseto the inserted transgenic DNA in the event MON87751 is characterizedherein as an insertion into a single locus in the soybean genome,resulting in two new loci or junction sequences between the inserted DNAand the soybean genome DNA. Also characterized herein are additionalunique sequences within the heterologous DNA inserted into the soybeangenome of event MON87751 and that are of sufficient length to be uniqueonly to a soybean genome comprising of the event MON87751 DNA. Thesejunction sequences are useful for detecting the presence of the eventMON87751 DNA in soybean cells, soybean tissue, soybean seed and soybeanplants or soybean plant products (soybean commodity products). DNAmolecular probes and primer pairs are described herein that have beendeveloped for use in identifying the presence of these various junctionsegments in biological samples containing or suspected of containingsoybean cells, soybean seed, soybean plant parts or soybean plant tissuethat contain the event MON87751 DNA. The data show that event MON87751contains a single T-DNA insertion with one copy of the insertedtransgenic DNA. No additional elements from the transformation construct1 other than portions of the Agrobacterium tumefaciens left and rightborder regions used for transgenic DNA transfer from the planttransformation plasmid to the soybean genome have been identified inevent MON87751 DNA. Finally, thermal amplification producing specificamplicons diagnostic for the presence of such event MON87751 DNA in asample, and DNA sequence analyses were performed to determine thearbitrarily assigned 5′ and 3′ insert-to-plant genome junctions, confirmthe organization of the elements within the insert, and determine thecomplete DNA sequence of the inserted transgene DNA (SEQ ID NO:9) insoybean event MON87751.

Dozens of transgenic events were produced using the transformationconstruct 1 used to produce the transgenic soybean event MON87751, andten additional transformation constructs were generated and used toproduce many dozens of other transgenic soybean events which werecompared to the soybean event MON87751 and similar soybean events. Theseevents were tested by ELISA assay for expression in leaf tissue of thetwo insecticidal proteins, Cry2Ab and Cry1A.105. A subset of the eventsproduced from each transformation, and most of the constructs, weretested for efficacy for controlling lepidopteran insect pests insmall-plot screenhouse trials. It was determined that the plantexpression elements, and relative orientation of the Cry2Ab andCry1A.105 expression cassettes in the transformation construct 1,provided the events with the best efficacy against the broadest spectrumof lepidopteran insect pests tested.

Unless otherwise noted herein, terms are to be understood according toconventional usage by those of ordinary skill in the relevant art.Definitions of common terms in molecular biology may also be found inRieger et al., Glossary of Genetics: Classical and Molecular, 5thedition, Springer-Verlag: New York, 1991; and Lewin, Genes V, OxfordUniversity Press: New York, 1994. As used herein, the term “soybean”means Glycine max and includes all plant varieties that can be bred withsoybean plants containing event MON87751 DNA, including wild soybeanspecies as well as those plants belonging to the genus Glycine thatpermit breeding between species. As used herein, the term “comprising”means “including but not limited to”.

The present invention provides for transgenic plants which have beentransformed with a DNA construct that contains at least two expressioncassettes; a first expression cassette expressing toxic amounts ofinsecticidal protein Cry2Ab, and a second expression cassette expressingtoxic amounts of insecticidal protein Cry1A.105. What is meant by toxicamount is an efficacious amount, an insecticidal amount, an efficaciousinsecticidal amount, an insecticidally effective amount, a target insectsuppressive amount, an efficacious pesticidal amount, an amount in thediet of insects of the order Lepidoptera that is insecticidal, and othersimilar terms to be understood according to conventional usage by thoseof ordinary skill in the relevant art. Soybean plants transformedaccording to the methods and with the DNA construct disclosed herein areresistant to lepidopteran insect pests. The linked agronomic traitsprovide ease in maintaining these traits together in a breedingpopulation, and exhibit resistance to a broader spectrum of lepidopteraninsect pests than plants containing only a single gene conferringresistance to lepidopteran insect pests (i.e., Cry1Ac).

A transgenic “plant” is produced by transformation of a plant cell withheterologous DNA, i.e., a polynucleic acid construct that includes anumber of efficacious features of interest; regeneration of a plantresulting from the insertion of the transgene into the genome of theplant cell, and selection of a particular plant characterized byinsertion into a particular genome location and the number ofefficacious features of the regenerated transgenic plant. The term“event” refers to DNA from the original transformant comprising theinserted DNA, and flanking genomic sequence immediately adjacent to theinserted DNA. Such DNA is unique and would be expected to be transferredto a progeny that receives the inserted DNA including the transgene ofinterest as the result of a sexual cross of one parental line thatincludes the inserted DNA (e.g., the original transformant and progenyresulting from selfing) and a parental line that does not contain theinserted DNA. The present invention also provides the originaltransformant plant and progeny of the transformant that include theheterologous DNA. Such progeny may be produced by a sexual outcrossbetween plants comprising the event and another plant wherein theprogeny includes the heterologous DNA. Even after repeated back-crossingto a recurrent parent, the event is present in the progeny of the crossat the same chromosomal location. The present invention is related tothe transgenic event, soybean plant comprising MON87751, progenythereof, and DNA compositions contained therein.

A “probe” is an isolated nucleic acid to which may be attached aconventional detectable label or reporter molecule, e.g., a radioactiveisotope, ligand, chemiluminescent agent, or enzyme. Such a probe iscomplementary to a strand of a target nucleic acid, in the case of thepresent invention, to a strand of DNA from MON87751 whether from aMON87751 containing plant or from a sample that includes MON87751 DNA.Probes according to the present invention include not onlydeoxyribonucleic or ribonucleic acids, but also polyamides and otherprobe materials that bind specifically to a target DNA sequence and canbe used to detect the presence of that target DNA sequence.

DNA primers are isolated polynucleic acids that are annealed to acomplementary target DNA strand by nucleic acid hybridization to form ahybrid between the primer and the target DNA strand, then extended alongthe target DNA strand by a polymerase, e.g., a DNA polymerase. A DNAprimer pair or a DNA primer set of the present invention refer to twoDNA primers useful for amplification of a target nucleic acid sequence,e.g., by the polymerase chain reaction (PCR) or other conventionalpolynucleic acid amplification methods.

DNA probes and DNA primers may be 11 polynucleotides or more in length,or may be 18 polynucleotides or more, 24 polynucleotides or more, or 30polynucleotides or more. Such probes and primers are selected to be ofsufficient length to hybridize specifically to a target sequence underhigh stringency hybridization conditions. Preferably, probes and primersaccording to the present invention have complete sequence similaritywith the target sequence, although probes differing from the targetsequence that retain the ability to hybridize to target sequences may bedesigned by conventional methods.

Primers and probes based on the flanking genomic DNA and insertsequences disclosed herein can be used to confirm (and, if necessary, tocorrect) the disclosed DNA sequences by conventional methods, e.g., byre-cloning and sequencing such DNA molecules.

The nucleic acid probes and primers of the present invention hybridizeunder stringent conditions to a target DNA molecule. Any conventionalnucleic acid hybridization or amplification method can be used toidentify the presence of DNA from a transgenic plant in a sample.Polynucleic acid molecules also referred to as nucleic acid segments orfragments thereof are capable of specifically hybridizing to othernucleic acid molecules under certain circumstances. As used herein, twopolynucleic acid molecules are said to be capable of specificallyhybridizing to one another if the two molecules are capable of formingan anti-parallel, double-stranded nucleic acid structure. A nucleic acidmolecule is said to be the “complement” of another nucleic acid moleculeif they exhibit complete complementarity. As used herein, molecules aresaid to exhibit “complete complementarity” when every nucleotide of oneof the molecules is complementary to a nucleotide of the other. Twomolecules are said to be “minimally complementary” if they can hybridizeto one another with sufficient stability to permit them to remainannealed to one another under at least conventional “low-stringency”conditions. Similarly, the molecules are said to be “complementary” ifthey can hybridize to one another with sufficient stability to permitthem to remain annealed to one another under conventional“high-stringency” conditions. Conventional stringency conditions aredescribed by Sambrook et al., 1989, and by Haymes et al., In: NucleicAcid Hybridization, A Practical Approach, IRL Press, Washington, D.C.(1985). Departures from complete complementarity are thereforepermissible, as long as such departures do not completely preclude thecapacity of the molecules to form a double-stranded structure. In orderfor a nucleic acid molecule to serve as a primer or probe it need onlybe sufficiently complementary in sequence to be able to form a stabledouble-stranded structure under the particular solvent and saltconcentrations employed.

As used herein, a substantially homologous sequence is a nucleic acidsequence that will specifically hybridize to the complement of thenucleic acid sequence to which it is being compared under highstringency conditions. Appropriate stringency conditions that promoteDNA hybridization, for example, 6.0× sodium chloride/sodium citrate(SSC) at about 45° C., followed by a wash of 2.0×SSC at 50° C., areknown to those skilled in the art or can be found in Current Protocolsin Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6. Forexample, the salt concentration in the wash step can be selected from alow stringency of about 2.0×SSC at 50° C. to a high stringency of about0.2×SSC at 50° C. In addition, the temperature in the wash step can beincreased from low stringency conditions at room temperature, about 22°C., to high stringency conditions at about 65° C. Both temperature andsalt may be varied, or either the temperature or the salt concentrationmay be held constant while the other variable is changed. In a preferredembodiment, a polynucleic acid of the present invention willspecifically hybridize to one or more of the nucleic acid molecules setforth in SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 17, 18, 19, 20, 21,22, 23, or 24, or complements thereof or fragments of either undermoderately stringent conditions, for example at about 2.0×SSC and about65° C. In a particularly preferred embodiment, a nucleic acid of thepresent invention will specifically hybridize to one or more of thenucleic acid molecules set forth in SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, 8,9, 10, 17, 18, 19, 20, 21, 22, 23, or 24 or complements or fragments ofeither under high stringency conditions. In one aspect of the presentinvention, a preferred marker nucleic acid molecule of the presentinvention has the nucleic acid sequence set forth in SEQ ID NO:1, or SEQID NO:2, or SEQ ID NO:3, or SEQ ID NO:4, or SEQ ID NO:5, or SEQ ID NO:6,or SEQ ID NO:7, or SEQ ID NO:8, or SEQ ID NO:9, or SEQ ID NO:10; or SEQID NO:17, or SEQ ID NO:18, OR SEQ ID NO:19, or SEQ ID NO:20, or SEQ IDNO:21, or SEQ ID NO:22, or SEQ ID NO: 23, or complements thereof orfragments of either. The hybridization of the probe to the target DNAmolecule can be detected by any number of methods known to those skilledin the art, these can include, but are not limited to, fluorescent tags,radioactive tags, antibody based tags, and chemiluminescent tags.

Regarding the amplification of a target nucleic acid sequence (e.g., byPCR) using a particular amplification primer pair, “stringentconditions” are conditions that permit the primer pair to hybridize onlyto the target nucleic acid sequence to which a primer having thecorresponding wild-type sequence (or its complement) would bind andpreferably to produce a unique amplification product, the amplicon, in aDNA thermal amplification reaction.

The term “specific for (a target sequence)” indicates that a probe orprimer hybridizes under stringent hybridization conditions only to thetarget sequence in a sample comprising the target sequence.

As used herein, “amplified DNA” or “amplicon” refers to the product ofpolynucleic acid amplification method directed to a target polynucleicacid molecule that is part of a polynucleic acid template. For example,to determine whether a soybean plant resulting from a sexual crosscontains transgenic plant genomic DNA from a soybean plant comprisingevent MON87751 of the present invention, DNA that is extracted from asoybean plant tissue sample may be subjected to a polynucleic acidamplification method using a primer pair that includes a first primerderived from a genomic DNA sequence in the region flanking theheterologous inserted DNA of event MON87751 and is elongated bypolymerase 5′ to 3′ in the direction of the inserted DNA. The secondprimer is derived from the heterologous inserted DNA molecule iselongated by the polymerase 5′ to 3′ in the direction of the flankinggenomic DNA from which the first primer is derived. The amplicon mayrange in length from the combined length of the primer pair plus onenucleotide base pair, or plus about fifty nucleotide base pairs, or plusabout two hundred-fifty nucleotide base pairs, or plus about fourhundred-fifty nucleotide base pairs or more. Alternatively, a primerpair can be derived from genomic sequence on both sides of the insertedheterologous DNA so as to produce an amplicon that includes the entireinsert polynucleotide sequence (e.g., a forward primer isolated from thegenomic portion on the 5′ end of SEQ ID NO:10 and a reverse primerisolated from the genomic portion on the 3′ end of SEQ ID NO:10 thatamplifies a DNA molecule comprising the inserted heterologous DNAsequence (SEQ ID NO:9) identified herein in the event MON87751containing genome). A member of a primer pair derived from the plantgenomic sequence adjacent to the inserted transgenic DNA is located adistance from the inserted DNA sequence, this distance can range fromone nucleotide base pair up to about twenty thousand nucleotide basepairs. The use of the term “amplicon” specifically excludes primerdimers that may be formed in the DNA thermal amplification reaction.

For practical purposes, one should design primers which produceamplicons of a limited size range, for example, between 100 to 1000bases. Smaller (shorter polynucleotide length) sized amplicons ingeneral are more reliably produced in thermal amplification reactions,allow for shorter cycle times, and can be easily separated andvisualized on agarose gels or adapted for use in endpoint TAQMAN®-likeassays. Smaller amplicons can be produced and detected by methods knownin the art of DNA amplicon detection. In addition, amplicons producedusing the primer pairs can be cloned into vectors, propagated, isolated,and sequenced or can be sequenced directly with methods well establishedin the art. Any primer pair derived from the combination of SEQ ID NO:7and SEQ ID NO:9 or the combination of SEQ ID NO:8 and SEQ ID NO:9 thatare useful in a DNA amplification method to produce an amplicondiagnostic for plants comprising MON87751 or progeny thereof is anaspect of the invention. Any single isolated DNA polynucleotide primermolecule comprising at least 15 contiguous nucleotides of SEQ ID NO:7,or its complement that is useful in a DNA amplification method toproduce an amplicon diagnostic for plants comprising MON87751 or progenythereof is an aspect of the invention. Any single isolated DNApolynucleotide primer molecule comprising at least 15 contiguousnucleotides of SEQ ID NO:8, or its complement that is useful in a DNAamplification method to produce an amplicon diagnostic for plantscomprising MON87751 or progeny thereof is an aspect of the invention.Any single isolated DNA polynucleotide primer molecule comprising atleast 15 contiguous nucleotides of SEQ ID NO:9, or its complement thatis useful in a DNA amplification method to produce an amplicondiagnostic for plants comprising MON87751 or progeny thereof is anaspect of the invention.

Polynucleic acid amplification can be accomplished by any of the variouspolynucleic acid amplification methods known in the art, including thepolymerase chain reaction (PCR). Amplification methods are known in theart and are described, inter alia, in U.S. Pat. Nos. 4,683,195 and4,683,202 and in PCR Protocols: A Guide to Methods and Applications, ed.Innis et al., Academic Press, San Diego, 1990. PCR amplification methodshave been developed to amplify up to 22 kb (kilobase) of genomic DNA andup to 42 kb of bacteriophage DNA (Cheng et al., Proc. Natl. Acad. Sci.USA 91:5695-5699, 1994). These methods as well as other methods known inthe art of DNA amplification may be used in the practice of the presentinvention. The sequence of the heterologous DNA insert or flankinggenomic DNA sequence from soybean event MON87751 can be verified (andcorrected if necessary) by amplifying such DNA molecules from soybeanseed containing event MON87751 DNA or soybean plants grown from thesoybean seed containing event MON87751 DNA deposited with the ATCChaving accession no. PTA-120166, using primers derived from thesequences provided herein, followed by standard DNA sequencing of thePCR amplicon or cloned DNA fragments thereof.

The diagnostic amplicon produced by these methods may be detected by aplurality of techniques. One such method is Genetic Bit Analysis(Nikiforov, et al. Nucleic Acid Res. 22:4167-4175, 1994) where a DNAoligonucleotide is designed that overlaps both the adjacent flankinggenomic DNA sequence and the inserted DNA sequence. The oligonucleotideis immobilized in wells of a microtiter plate. Following PCR of theregion of interest (using one primer in the inserted sequence and one inthe adjacent flanking genomic sequence), a single-stranded PCR productcan be hybridized to the immobilized oligonucleotide and serve as atemplate for a single base extension reaction using a DNA polymerase andlabeled dideoxynucleotide triphosphates (ddNTPs) specific for theexpected next base. Readout may be fluorescent or ELISA-based. A signalindicates presence of the transgene/genomic sequence due to successfulamplification, hybridization, and single base extension.

Another method is the Pyrosequencing technique as described by Winge(Innov. Pharma. Tech. 00:18-24, 2000). In this method an oligonucleotideis designed that overlaps the adjacent genomic DNA and insert DNAjunction. The oligonucleotide is hybridized to single-stranded PCRproduct from the region of interest (one primer in the inserted sequenceand one in the flanking genomic sequence) and incubated in the presenceof a DNA polymerase, ATP, sulfurylase, luciferase, apyrase, adenosine 5′phosphosulfate and luciferin. DNTPs are added individually and theincorporation results in a light signal that is measured. A light signalindicates the presence of the transgene/genomic sequence due tosuccessful amplification, hybridization, and single or multi-baseextension.

Fluorescence Polarization as described by Chen, et al., (Genome Res.9:492-498, 1999) is a method that can be used to detect the amplicon ofthe present invention. Using this method an oligonucleotide is designedthat overlaps the genomic flanking and inserted DNA junction. Theoligonucleotide is hybridized to single-stranded PCR product from theregion of interest (one primer in the inserted DNA and one in theflanking genomic DNA sequence) and incubated in the presence of a DNApolymerase and a fluorescent-labeled ddNTP. Single base extensionresults in incorporation of the ddNTP. Incorporation can be measured asa change in polarization using a fluorometer. A change in polarizationindicates the presence of the transgene/genomic sequence due tosuccessful amplification, hybridization, and single base extension.

Taqman® (PE Applied Biosystems, Foster City, Calif.) is described as amethod of detecting and quantifying the presence of a DNA sequence andis fully understood in the instructions provided by the manufacturer.Briefly, a FRET oligonucleotide probe is designed that overlaps thegenomic flanking and insert DNA junction. The FRET probe and PCR primers(one primer in the insert DNA sequence and one in the flanking genomicsequence) are cycled in the presence of a thermalstable polymerase anddNTPs. Hybridization of the FRET probe results in cleavage and releaseof the fluorescent moiety away from the quenching moiety on the FRETprobe. A fluorescent signal indicates the presence of thetransgene/genomic sequence due to successful amplification andhybridization.

Molecular Beacons have been described for use in sequence detection asdescribed in Tyangi, et al. (Nature Biotech. 14:303-308, 1996). Briefly,a FRET oligonucleotide probe is designed that overlaps the flankinggenomic and insert DNA junction. The unique structure of the FRET proberesults in it containing secondary structure that keeps the fluorescentand quenching moieties in close proximity. The FRET probe and PCRprimers (one primer in the insert DNA sequence and one in the flankinggenomic sequence) are cycled in the presence of a thermalstablepolymerase and dNTPs. Following successful PCR amplification,hybridization of the FRET probe to the target sequence results in theremoval of the probe secondary structure and spatial separation of thefluorescent and quenching moieties. A fluorescent signal results. Afluorescent signal indicates the presence of the flanking/transgeneinsert sequence due to successful amplification and hybridization.

DNA detection kits that are based on DNA amplification methods containDNA primer molecules that hybridize specifically to a target DNA andamplify a diagnostic amplicon under the appropriate reaction conditions.The kit may provide an agarose gel based detection method or any numberof methods of detecting the diagnostic amplicon that are known in theart. DNA detection kits can be developed using the compositionsdisclosed herein and are useful for identification of soybean eventMON87751 DNA in a sample and can be applied to methods for breedingsoybean plants containing event MON87751 DNA. A kit that contains DNAprimers that are homologous or complementary to any portion of thesoybean genomic region as set forth in SEQ ID NO:10 and to any portionof the inserted transgenic DNA as set forth in SEQ ID NO:10 is an objectof the invention. The DNA molecules can be used in DNA amplificationmethods (PCR) or as probes in polynucleic acid hybridization methods,i.e., Southern analysis, northern analysis.

Theinvention thus provides a DNA molecule that contains at least one of thenucleotide sequences provided as SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3,SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ IDNO:9, SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ IDNO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ IDNO:25, and SEQ ID NO:26. Any segment of DNA derived from transgenicsoybean event MON87751 that is sufficient to include at least one of thesequences provided as SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ IDNO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9,SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20,SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, orSEQ ID NO:26 is within the scope of the invention. In addition, anypolynucleotide comprising a sequence complementary to any of thesequences described within this paragraph is within the scope of theinvention.

The invention provides exemplary DNA molecules that can be used eitheras primers or probes for detecting the presence of DNA derived from asoybean plant comprising event MON87751 DNA in a sample. Such primers orprobes are specific for a target nucleic acid sequence and as such areuseful for the identification of soybean event MON87751 nucleic acidsequence by the methods of the invention described herein.

A “primer” may be a highly purified, isolated polynucleotide that isdesigned for use in specific annealing or hybridization methods thatinvolve thermal amplification. A pair of primers may be used withtemplate DNA, such as a sample of soybean genomic DNA, in a thermalamplification, such as polymerase chain reaction (PCR), to produce anamplicon, where the amplicon produced from such reaction would have aDNA sequence corresponding to sequence of the template DNA locatedbetween the two sites where the primers hybridized to the template. Asused herein, an “amplicon” is a replication of a piece or fragment ofDNA that has been synthesized using amplification techniques. Anamplicon of the invention may comprise at least one of the sequencesprovided as provided as SEQ ID NO:11 or SEQ ID NO:12. A primer istypically designed to hybridize to a complementary target DNA strand toform a hybrid between the primer and the target DNA strand, and thepresence of the primer is a point of recognition by a polymerase tobegin extension of the primer (i.e., polymerization of additionalnucleotides into a lengthening nucleotide molecule) using as a templatethe target DNA strand. Primer pairs, as used in the invention, areintended to refer to use of two primers binding opposite strands of adouble stranded nucleotide segment for the purpose of amplifyinglinearly the polynucleotide segment between the positions targeted forbinding by the individual members of the primer pair, typically in athermal amplification reaction or other conventional nucleic-acidamplification methods. Exemplary DNA molecules useful as primers areprovided as SEQ ID NO:11, SEQ ID NO:12, SEQ ID NO:14, or SEQ ID NO:15.The primer pair provided as SEQ ID NO:11 and SEQ ID NO:12 are useful asa first DNA molecule and a second DNA molecule that is different fromthe first DNA molecule, and both are each of sufficient length ofcontiguous nucleotides of SEQ ID NO:10 to function as DNA primers that,when used together in a thermal amplification reaction with template DNAderived from soybean event MON87751, to produce an amplicon diagnosticfor soybean event MON87751 DNA in a sample.

A “probe” is an isolated nucleic acid that is complementary to a strandof a target nucleic acid. Probes according to the invention include notonly deoxyribonucleic or ribonucleic acids but also polyamides and otherprobe materials that bind specifically to a target DNA sequence and thedetection of such binding can be useful in diagnosing, discriminating,determining, or confirming the presence of that target DNA sequence in aparticular sample. A probe may be attached to a conventional detectablelabel or reporter molecule, e.g., a radioactive isotope, ligand,chemiluminescent agent, or enzyme. An exemplary DNA molecule useful as aprobe is provided as SEQ ID NO:13 and SEQ ID NO:16.

Probes and primers according to the invention may have complete sequenceidentity with the target sequence, although primers and probes differingfrom the target sequence that retain the ability to hybridizepreferentially to target sequences may be designed by conventionalmethods. In order for a nucleic acid molecule to serve as a primer orprobe it need only be sufficiently complementary in sequence to be ableto form a stable double-stranded structure under the particular solventand salt concentrations employed. Any conventional nucleic acidhybridization or amplification method can be used to identify thepresence of transgenic DNA from soybean event MON87751 in a sample.Probes and primers are generally at least about 11 nucleotides, at leastabout 18 nucleotides, at least about 24 nucleotides, or at least about30 nucleotides or more in length. Such probes and primers hybridizespecifically to a target DNA sequence under stringent hybridizationconditions. Conventional stringency conditions are described by Sambrooket al., 1989, and by Haymes et al., In: Nucleic Acid Hybridization, APractical Approach, IRL Press, Washington, D.C. (1985).

Any number of methods well known to those skilled in the art can be usedto isolate and manipulate a DNA molecule, or fragment thereof, disclosedin the invention, including thermal amplification methods. DNAmolecules, or fragments thereof, can also be obtained by othertechniques such as by directly synthesizing the fragment by chemicalmeans, as is commonly practiced by using an automated oligonucleotidesynthesizer.

The DNA molecules and corresponding nucleotide sequences provided hereinare therefore useful for, among other things, identifying soybean eventMON87751, selecting plant varieties or hybrids comprising soybean eventMON87751, detecting the presence of DNA derived from the transgenicsoybean event MON87751 in a sample, and monitoring samples for thepresence and/or absence of soybean event MON87751 or plant parts derivedfrom soybean plants comprising event MON87751.

The invention provides soybean plants, soybean plant cells, soybeanseeds, soybean plant parts (such as pollen, ovule, pod, flower tissue,root tissue, stem tissue, and leaf tissue), soybean progeny plants,soybean oil, soybean wine, soybean milk, soybean protein, and soybeancommodity products. These soybean plants, soybean plant cells, soybeanseeds, soybean plant parts, soybean progeny plants, soybean oil, soybeanwine, soybean milk, soybean protein, and soybean commodity productscontain a detectable amount of a polynucleotide of the invention, i.e.,such as a polynucleotide having at least one of the sequences providedas SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10; SEQ IDNO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ IDNO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, or SEQ ID NO:26.Soybean plants, plant cells, seeds, plant parts, and progeny plants ofthe invention may also contain one or more additional transgenes. Suchadditional transgene may be any nucleotide sequence encoding a proteinor RNA molecule conferring a desirable trait including but not limitedto increased insect resistance, increased water use efficiency,increased yield performance, increased drought resistance, increasedseed quality, improved nutritional quality, and/or increased herbicidetolerance, in which the desirable trait is measured with respect to asoybean plant lacking such additional transgene.

The invention provides soybean plants, soybean plant cells, soybeanseeds, soybean plant parts (such as pollen, ovule, pod, flower tissue,root tissue, stem tissue, and leaf tissue), soybean progeny plantsderived from a transgenic soybean plant containing event MON87751 DNA. Arepresentative sample of soybean seed containing event MON87751 DNA hasbeen deposited according to the Budapest Treaty with the American TypeCulture Collection (ATCC®). The ATCC repository has assigned the PatentDeposit Designation PTA-120166 to the seed containing event MON87751DNA.

The invention provides a microorganism comprising a DNA molecule havingat least one sequence selected from SEQ ID NO:1, SEQ ID NO:2, SEQ IDNO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8,SEQ ID NO:9, SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ IDNO:25, and SEQ ID NO:26 present in its genome. An example of such amicroorganism is a transgenic plant cell. Microorganisms, such as aplant cell of the invention, are useful in many industrial applications,including but not limited to: (i) use as research tool for scientificinquiry or industrial research; (ii) use in culture for producingendogenous or recombinant carbohydrate, lipid, nucleic acid, or proteinproducts or small molecules that may be used for subsequent scientificresearch or as industrial products; and (iii) use with modern planttissue culture techniques to produce transgenic plants or plant tissuecultures that may then be used for agricultural research or production.The production and use of microorganisms such as transgenic plant cellsutilizes modern microbiological techniques and human intervention toproduce a man-made, unique microorganism. In this process, recombinantDNA is inserted into a plant cell's genome to create a transgenic plantcell that is separate and unique from naturally occurring plant cells.This transgenic plant cell can then be cultured much like bacteria andyeast cells using modern microbiology techniques and may exist in anundifferentiated, unicellular state. The transgenic plant cell's newgenetic composition and phenotype is a technical effect created by theintegration of the heterologous DNA into the genome of the cell. Anotheraspect of the invention is a method of using a microorganism of theinvention. Methods of using microorganisms of the invention, such astransgenic plant cells, include (i) methods of producing transgeniccells by integrating recombinant DNA into the genome of the cell andthen using this cell to derive additional cells possessing the sameheterologous DNA; (ii) methods of culturing cells that containrecombinant DNA using modern microbiology techniques; (iii) methods ofproducing and purifying endogenous or recombinant carbohydrate, lipid,nucleic acid, or protein products from cultured cells; and (iv) methodsof using modern plant tissue culture techniques with transgenic plantcells to produce transgenic plants or transgenic plant tissue cultures.

Plants of the invention may pass along the event MON87751 DNA, includingthe transgene inserted in soybean event MON87751, to progeny. As usedherein, “progeny” includes any plant, seed, plant cell, and/orregenerable plant part comprising the event MON87751 DNA derived from anancestor plant and/or comprising a DNA molecule having at least onesequence selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2,SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ IDNO:8, SEQ ID NO:9, SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQ IDNO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ IDNO:24, SEQ ID NO:25, and SEQ ID NO:26. Plants, progeny, and seeds may behomozygous or heterozygous for the transgene. Progeny may be grown fromseeds produced by a soybean event MON87751 containing plant and/or fromseeds produced by a plant fertilized with pollen from a soybean eventMON87751 containing plant.

Progeny plants may be self-pollinated (also known as “selfing”) togenerate a true breeding line of plants, i.e., plants homozygous for thetransgene. Selfing of appropriate progeny can produce plants that arehomozygous for both added, exogenous genes.

Alternatively, progeny plants may be out-crossed, e.g., bred withanother unrelated plant, to produce a varietal or a hybrid seed orplant. The other unrelated plant may be transgenic or non-transgenic. Avarietal or hybrid seed or plant of the invention may thus be derived bysexually crossing a first parent that lacks the specific and unique DNAof the soybean event MON87751 with a second parent comprising soybeanevent MON87751, resulting in a hybrid comprising the specific and uniqueDNA of the soybean event MON87751. Each parent can be a hybrid or aninbred/varietal, so long as the cross or breeding results in a plant orseed of the invention, i.e., a seed having at least one allelecontaining the DNA of soybean event MON87751 and/or a DNA moleculehaving at least one sequence selected from SEQ ID NO:1, SEQ ID NO:2, SEQID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ IDNO:8, SEQ ID NO:9, SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQ IDNO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ IDNO:24, SEQ ID NO:25, and SEQ ID NO:26. Two different transgenic plantsmay thus be crossed to produce hybrid offspring that contain twoindependently segregating, added, exogenous genes. For example, theMON87751 containing Cry2Ab and Cry1A.105 conferring dual mode of actioninsect resistance to soybean can be crossed with other transgenicsoybean plants to produce a plant having the characteristics of bothtransgenic parents. One example of this would be a cross of MON87751containing Cry2Ab and Cry1A.105 conferring dual mode of action insectresistance to soybean with a plant having one or more additional traitssuch as herbicide tolerance (e.g. soybean event MON89788 or soybeanevent MON 87708) and/or insect control (e.g. soybean event MON 88701),resulting in a progeny plant or seed that has dual mode of actionresistance to lepidopteran insect pests and has at least one or moreadditional traits. Back-crossing to a parental plant and out-crossingwith a non-transgenic plant are also contemplated, as is vegetativepropagation. Descriptions of other breeding methods that are commonlyused for different traits and crops can be found in one of severalreferences, e.g., Fehr, in Breeding Methods for Cultivar Development,Wilcox J. ed., American Society of Agronomy, Madison Wis. (1987).

Anysuch commodity product that is derived from soybean plants comprisingevent MON87751 may contain at least a detectable amount of the specificand unique DNA corresponding to soybean event MON87751, and specificallymay contain a detectable amount of a polynucleotide comprising a DNAmolecule having at least one sequence selected from SEQ ID NO:1, SEQ IDNO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7,SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ IDNO:24, SEQ ID NO:25, and SEQ ID NO:26. Any standard method of detectionfor nucleotide molecules may be used, including methods of detectiondisclosed herein. A commodity product is within the scope of theinvention if there is any detectable amount of a DNA molecule having atleast one sequence selected from SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3,SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ IDNO:9, SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ IDNO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ IDNO:25, and SEQ ID NO:26 in the commodity product.

The plants, progeny, seeds, plant cells, plant parts (such as pollen,ovule, pod, flower, root or stem tissue, and leaves), and commodityproducts of the invention are therefore useful for, among other things,growing plants for the purpose of producing seed and/or plant partscomprising soybean event MON87751 for agricultural purposes, producingprogeny comprising soybean event MON87751 for plant breeding andresearch purposes, use with microbiological techniques for industrialand research applications, and sale to consumers.

Methods for producing an insect resistant soybean plant comprising theDNA sequences specific and unique to event MON87751 of the invention areprovided. Transgenic plants used in these methods may be homozygous orheterozygous for the transgene. Progeny plants produced by these methodsmay be varietal or hybrid plants; may be grown from seeds produced by asoybean event MON87751 containing plant and/or from seeds produced by aplant fertilized with pollen from a soybean event MON87751 containingplant; and may be homozygous or heterozygous for the transgene. Progenyplants may be subsequently self-pollinated to generate a true breedingline of plants, i.e., plants homozygous for the transgene, oralternatively may be out-crossed, e.g., bred with another unrelatedplant, to produce a varietal or a hybrid seed or plant.

Methods of detecting the presence of DNA derived from a soybean cell,soybean tissue, soybean seed, or soybean plant comprising soybean eventMON87751 in a sample are provided. One method consists of (i) extractinga DNA sample from at least one soybean cell, soybean tissue, soybeanseed, or soybean plant, (ii) contacting the DNA sample with at least oneprimer that is capable of producing DNA sequence specific to eventMON87751 DNA under conditions appropriate for DNA sequencing, (iii)performing a DNA sequencing reaction, and then (iv) confirming that thenucleotide sequence comprises a nucleotide sequence specific for eventMON87751, or the construct comprised therein, such as one selected fromthe group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ IDNO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9,SEQ ID NO:10; SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20,SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25,and SEQ ID NO:26. Another method consists of (i) extracting a DNA samplefrom at least one soybean cell, soybean tissue, soybean seed, or soybeanplant, (ii) contacting the DNA sample with a primer pair that is capableof producing an amplicon from event MON87751 DNA under conditionsappropriate for DNA amplification, (iii) performing a DNA amplificationreaction, and then (iv) detecting the amplicon molecule and/orconfirming that the nucleotide sequence of the amplicon comprises anucleotide sequence specific for event MON87751, such as one selectedfrom the group consisting of SEQ ID NO: 1, SEQ ID NO:2, SEQ ID NO:3, SEQID NO:4, SEQ ID NO:5, and SEQ ID NO:6.

The detection of a nucleotide sequence specificfor event MON87751 in the amplicon is determinative and/or diagnosticfor the presence of the soybean event MON87751 specific DNA in thesample. An example of a primer pair that is capable of producing anamplicon from event MON87751 DNA under conditions appropriate for DNAamplification is provided as SEQ ID NO:11, and SEQ ID NO:12. Otherprimer pairs may be readily designed by one of skill in the art andwould produce an amplicon comprising SEQ ID NO: 1, or SEQ ID NO:2, orSEQ ID NO:3, or SEQ ID NO:4, or SEQ ID NO:5, or SEQ ID NO:6, whereinsuch a primer pair comprises at least one primer within the genomicregion flanking the insert and a second primer within the insert.Another method of detecting the presence of DNA derived from a soybeancell, soybean tissue, soybean seed, or soybean plant comprising soybeanevent MON87751 in a sample consists of (i) extracting a DNA sample fromat least one soybean cell, soybean tissue, soybean seed, or soybeanplant, (ii) contacting the DNA sample with a DNA probe specific forevent MON87751 DNA, (iii) allowing the probe and the DNA sample tohybridize under stringent hybridization conditions, and then (iv)detecting hybridization between the probe and the target DNA sample. Anexample of the sequence of a DNA probe that is specific for eventMON87751 DNA is provided as SEQ ID NO:13 or SEQ ID NO:16. Other probesmay be readily designed by one of skill in the art and would comprise atleast one fragment of genomic DNA flanking the insert and at least onefragment of insert DNA, such as sequences provided in, but not limitedto, SEQ ID NO: 1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5,SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, and SEQ ID NO:10. Detection ofprobe hybridization to the DNA sample is diagnostic for the presence ofsoybean event MON87751 specific DNA in the sample. Absence ofhybridization is alternatively diagnostic of the absence of soybeanevent MON87751 specific DNA in the sample.

DNA detection kits are provided that are useful for the identificationof soybean event MON87751 DNA in a sample and can also be applied tomethods for breeding soybean plants containing the appropriate eventDNA. Such kits contain DNA primers and/or probes comprising fragments ofSEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ IDNO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10; SEQ ID NO:17,SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22,SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, and SEQ ID NO:26. One exampleof such a kit comprises at least one DNA molecule of sufficient lengthof contiguous nucleotides of SEQ ID NO:10 to function as a DNA probeuseful for detecting the presence and/or absence of DNA derived fromtransgenic soybean plants comprising event MON87751 in a sample. The DNAderived from transgenic soybean plants comprising event MON87751 wouldcomprise a DNA molecule having at least one sequence selected from SEQID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ IDNO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10; SEQ ID NO:17,SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22,SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, and SEQ ID NO:26. A DNAmolecule sufficient for use as a DNA probe is provided that is usefulfor determining, detecting, or diagnosing the presence and/or absence ofsoybean event MON87751 DNA in a sample is provided as SEQ ID NO:13.Other probes may be readily designed by one of skill in the art andshould comprise at least 15, at least 16, at least 17, at least 18, atleast 19, at least 20, at least 21, at least 22, at least 23, at least24, at least 25, at least 26, at least 27, at least 28, at least 29, atleast 30, at least 31, at least 32, at least 33, at least 34, at least35, at least 36, at least 37, at least 38, at least 39, or at least 40contiguous nucleotides of SEQ ID NO:10 and be sufficiently unique tosoybean event MON87751 DNA in order to identify DNA derived from theevent.

Such a method may alsoinclude sequencing the amplicon or a fragment thereof, which would bedeterminative of, i.e. diagnostic for, the presence of the soybean eventMON87751 specific DNA in the target DNA sample. Other primer pairs maybe readily designed by one of skill in the art and should comprise atleast 15, at least 16, at least 17, at least 18, at least 19, at least20, at least 21, at least 22, at least 23, at least 24, at least 25, atleast 26, at least 27, at least 28, at least 29, or at least 30contiguous nucleotides of sequences provided in, but not limited to SEQID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ IDNO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10; SEQ ID NO:17,SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22,SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, and SEQ ID NO:26 and besufficiently unique to soybean event MON87751 DNA in order to identifyDNA derived from the event.

Example 1

This example describes the transformation and selection of soybean eventMON87751. The expression of foreign genes in plants is known to beinfluenced by their chromosomal position, perhaps due to chromatinstructure (e.g., heterochromatin) or the proximity of transcriptionalregulation elements (e.g., enhancers) close to the integration site(Weising, 1988). For this reason, it is often necessary to screen alarge number of events in order to identify an event characterized byoptimal expression of an introduced gene of interest. For example, ithas been observed in plants and in other organisms that there may bewide variation in the levels of expression of an introduced gene amongevents. There may also be differences in spatial or temporal patterns ofexpression, for example, differences in the relative expression of atransgene in various plant tissues, that may not correspond to thepatterns expected from transcriptional regulatory elements present inthe introduced gene construct. For these reasons, eleven differentexpression vectors were generated and tested in transformed soybeanduring the selection of event MON87751.

Eleven different expression constructs were transformed and tested inplants. The individual expression constructs varied in the combinationof the use of expression elements, i.e., enhancer (E), promoter (P),leader (L), introns (I), chloroplast targeting peptide (CTP), and 3′transcription termination and polyadenylation signal (T). Also, T-DNAsegments contained two expression cassettes encoding both Cry proteins(Cry2Ab and Cry1A.105), or contained one expression cassette encoding asingle Cry protein, i.e., Cry2Ab or Cry1A.105. A further variation inthe expression constructs with the T-DNA segments containing both Cry2Aband Cry1A.105 expression cassettes was the relative orientation of thetwo cassettes encoding the Cry proteins. Specifically, the two Cryprotein expression cassettes were either positioned in a relative tandemorientation of transcription so that expression from each promoter ofthe respective Cry proteins proceeds in the same direction, but eachfrom their separate respective promoters (see FIG. 2), or the two Cryprotein expression cassettes were in a reversed orientation so thatexpression from each promoter of the two Cry proteins is away from apoint centered between the two promoters, i.e., transcription of eachCry protein expression cassette proceeds in opposite directions and doesnot converge (see FIG. 2). The DNA sequence encoding Cry1A.105 wassequence diversified in constructs 4, 6, 7, 8, and 9, compared toconstructs 1 and 3. In yet a further variation, in two of the constructswith the two Cry expression cassettes oriented in reverse orientation oftranscription, transcription enhancers were positioned between thediverging promoters (see FIG. 2).

The eleven expression constructs were transformed at three separatetimes, by Agrobacterium-mediated transformation of soybean meristemtissue. The method was described in U.S. Pat. No. 8,030,544, whichallows for the generation of transformed plants without utilization ofcallus. Briefly, meristem tissues were excised from the embryos ofgerminated A3555 soybean seed (Asgrow, St Louis, Mo.). Construct 1comprised two separate T-DNA segments, each bounded by Agrobacteriumborder sequences (T-DNA segment). The first T-DNA segment of thetransformation construct contained two expression cassettes with thefirst expression cassette encoding a region of the Tn7adenylyltransferase gene from Escherichia coli (which confersspectinomycin and streptomycin resistance; aadA-SPR) and is used forselection; and the second expression cassette encoding a region of thesucrose phosphorylase gene from Agrobacterium tumefaciens strain C58(which catalyzes the conversion of sucrose to fructose andglucose-1-phosphate; STR+OriRi) and is used as a scorable marker. Thesecond T-DNA segment of the different transformation constructscontained either one expression cassette encoding only Cry2Ab(constructs 2, 5, 10 or 11) or an expression cassette encoding onlyCry1A.105 (constructs 3 or 6); or the second T-DNA segment of thedifferent transformation constructs contained one expression cassetteencoding Cry2Ab and one expression cassette encoding Cry1A.105(constructs 1, 4, 7, 8, or 9) (illustrated in FIG. 2). Because eachT-DNA segment of the transformation construct is bounded by separateAgrobacterium border sequences, the T-DNA segment comprising theselection and scorable marker cassettes may integrate into the soybeancell genome at a site that is different from the site of integration ofthe T-DNA segment encoding the Cry2Ab and/or Cry1A.105 expressioncassettes. Thus, events can be screened for segregation and loss of theselection and scorable marker sequences. All events were selected forabsence of the backbone and absence of the selection/scorable markercassette sequences. After co-culturing with Agrobacterium carrying thetransformation construct, the meristems were placed on selection mediumcontaining spectinomycin, carbenicillin disodium salt, cefotaxime sodiumsalt, and ticarcillin disodium salt/potassium clavulanate mixture toinhibit the growth of untransformed plant cells and excessAgrobacterium. The meristems were then placed in media conducive toshoot and root development. Rooted plants (R0) with normal phenotypiccharacteristics were selected and transferred to soil for growth andfurther assessment.

The expression construct 1, used to generate event MON87751, contained aT-DNA segment encoding two different Cry proteins, in a 5′ to 3′relative order of plant expression elements (with or without interveningsequences): a promoter, leader and first intron derived from theArabidopsis thaliana Actin 2 gene (P-At.Act2), a chimeric codingsequence comprised of the N-terminal chloroplast transit peptide codingsequence derived from the Arabidopsis 5-enolpyruvylshikimate-3-phosphatesynthase (EPSPS) gene fused in frame to a gene encoding Cry2Ab (whichencodes a protein that confers insect resistance) from Bacillusthuringiensis (Bt) with nucleotides modified for plant expression(CTP2-Cry2Ab), a 3′ transcription termination and polyadenylationelement (3′ UTR) derived from an Oryza sativa metallothionein-likeprotein gene (T.OsMth), an intervening sequence between the first Cryprotein expression cassette and the second Cry protein expressioncassette; a promoter and leader derived from the Arabidopsis ribulose1,5-bisphosphate carboxylase small subunit 1A gene (P-At.RbcS4), thispromoter-leader is linked to a chimeric coding sequence comprised ofchloroplast transit peptide coding sequence derived from the Arabidopsisribulose 1,5-bisphosphate carboxylase small subunit 1A protein gene(CTP1) which also contained coding sequence encoding a repeat of thetransit peptide cleavage site and 3 amino acids from the mature proteinfused in frame with a gene encoding Cry1A.105 (which encodes a proteinthat confers insect resistance), composed of segments of genes encodingCry1Ab1 (domains I & II), Cry1Fa1 (domain III), and Cry1Ac1 (protoxindomain) from Bacillus thuringiensis (Bt) with nucleotides modified forplant expression, a 3′ UTR (T-Mt.Pt1) derived from the Medicagotruncatula phosphate transporter 1 gene. In the construct 1 expressioncassette, the T-DNA cassette containing the two separate Cry2Ab andCry1A.105 expression cassettes has an Agrobacterium right border on thearbitrarily designated 5′ end, which is 5′ to the Cry2Ab cassette; andan Agrobacterium left border on the arbitrarily designated 3′ end, whichis 3′ to the Cry1A.105 cassette. The Cry2Ab cassette (promoter throughterminator) is at positions 123-3785 in SEQ ID NO:9, and the Cry1A.105cassette (promoter through terminator) is at positions 3831-9754 in SEQID NO:9.

The T-DNA cassette for construct 2 (Cry2Ab) and for construct 3(Cry1A.105) contained single Cry-protein encoding cassettes with thesame elements for the respective Cry-protein encoding genes used inconstruct 1, see FIG. 2.

Constructs 4, 5, and 6 were similar in element orientation to constructs1, 2, and 3, respectively, but with differing promoter-leader-intron andchloroplast transit peptide for both the Cry2Ab and Cry1A.105 cassettes.The terminators for the corresponding Cry protein cassettes (Cry2Ab withT-Os.Mth, or Cry1A.105 with T-Mt.Pt1) were identical in all expressionconstructs 1 through 11 (see FIG. 2).

The promoter-leader-intron and chloroplast transit peptide, Cry-proteinencoding sequence, and terminator used for both the Cry2Ab and Cry1A.105cassettes in each of the constructs 7-11 were identical to those used inconstructs 4, 5, and 6. However, for constructs 7, 8, and 9 theorientation of the Cry2Ab cassette and the Cry1A.105 cassette wereinverted or reversed relative to one another and the orientation oftranscription was in opposite directions, each from their respectivepromoters, see FIG. 2. Constructs 7, 8, and 9 differed in the absence(construct 7) of an enhancer between the two cassettes, or the presenceof an enhancer; construct 8 with enhancer 1 (E1), or construct 9 withenhancer 2 (E2), see FIG. 2. Construct 10 and construct 11 were singleCry2Ab cassettes with either E1 (construct 10) or E2 (construct 11).

Following transformation, and transfer of (R0) events to soil, extensivemolecular, agronomic, and phenotypic analysis was done to select eventsfor further testing. Additionally, events were self-pollinated and theresulting seed from the selected events was used for field andadditional molecular testing.

The molecular testing included the following: assays to determine copynumber, assays to determine integrity of both Cry protein containingexpression cassettes (constructs 1, 4, 7, 8, and 9), presence of Cryprotein encoding T-DNA cassette (single Cry protein expression cassettes(constructs 2, 3, 6, 10, or 11) or two Cry protein expression cassettes(constructs 1, 4, 7, 8, or 9)); assays to determine protein expressionas measured by ELISA, and assays to determine segregation ratio of theT-DNA expression cassette (1:2:1 or 1:3). Agronomic assays included (forR0 events generated from constructs 1, 2, and 3, insect efficacy by leafdisc bioassay for two pest species (Anticarsia gemmatalis (velvetbeancaterpillar, VBC) and Chrysodeixis includens (soybean looper, SBL)). R0plants were grown to maturity, events were self-pollinated, and seed setfor each event was determined.

The number of R0 events generated by transformation with the 11individual constructs and transferred to soil varied, and ranged from420 events to greater than 5000 events (see Table 1). For thetransformation with the construct 1, from which event MON87751 wasgenerated, there were a total of 1102 R0 plants rooted into soil, ofwhich from these only 281 events passed the initial molecular analysis.The additional molecular, agronomic and phenotypic analysis of these 281events which were generated by transformation with construct 1 resultedin only 29 R1 events evaluated for additional greenhouse analysis.

For the 29 R1 events generated from transformation with construct 1 andevaluated for further analysis, the R1 seed was planted in a greenhousefor analysis of the R1 events with assays including: (a) R1 germination(100% germination); (b) identification of homozygous plants; (c)confirmation PCR analysis that the homozygous plants no longer containedthe selection/scorable marker sequence (it had segregatedindependently); (d) insect efficacy as determined by leaf disc bioassayfor C. includens (SBL); and (e) insect efficacy as determined by leafdisc bioassay for Spodoptera frugiperda (fall armyworm, FAW), (f)protein expression by ELISA analysis on V7 stage leaf tissue, advancingevents with Cry2Ab and Cry1A.105 protein levels over >4 ppm. In additionto the molecular analysis and insect leaf disc bioassay results,agronomic phenotype observations and seed set from four selections/eventwere collected. Based on the totality of these data, R2 seed from 21 ofR1 events generated by transformation with construct 1 were evaluated inagronomic field trials and efficacy screenhouse trials.

Example 2

Agronomic field trials were designed to evaluate the phenotypiccharacteristics and yield of soybean events expressing Cry2Ab andCry1A.105 compared to the control, A3555 (parental background). In theseagronomic field trials, the controls and events were of soybean varietyA3555, with a relative maturity group 3 (RM3). The trials were plantedunder a randomized complete block design (RCBD) over four seasons andtwo geographic locations. In one geographic location the agronomic fieldtrials were conducted at 25 field sites in each season, and in a secondgeographic location the agronomic field trials were conducted at 14field sites in each season. Standard agronomic practices were followedin the planting and data collection for all trials. The data collectedincluded emergence rating, seedling vigor, flowering date, flower colorobservation, phenotype observation, pubescence color, maturity, lodging,plant height, shattering score, harvest date, seed weight/plot, seedmoisture/plot, and yield in bushels per acre (bu/ac).

For data analysis, some locations were dropped due to pre-harvestquality issues (i.e., standing water, inadequate soil moisture, pooremergence, late season pod shattering due to hail storm), or somelocations were dropped due to a coefficient of variation (CV) above 15%and/or a high location quality index (LQI).

Across all locations tested, the phenotype measures taken indicated thatthe agronomic ratings for the events were within the normal range of thecontrol, A3555. Not all observations were taken at all sites and somedata, for example emergence, may have been collected but yield was notdetermined because the location was dropped for issues which occurredpost collection of the early phenotype data.

For the agronomic field trials, the number of events generated byconstruct 1, 2, 3, 4, 5, or 6 and tested at each field trial in twogeographic locations, and the soybean event generation tested (i.e. R3,R4, R5, R6, or R7) is shown in Table 2.

Meta analysis of agronomic field trials for events tested across eachseason, each geographic location, and each field trial testing meanyield (bu/acre) demonstrated that there was a statistically significantincrease in yield for event MON87751 compared to control A3555 (Table2). The events expressing only Cry2Ab did not have a statisticallysignificant difference in yield compared to the control A3555, see Table3. The event expressing only Cry1A.105 had a statistically significantdecrease in yield compared to the control A3555, see Table 3.

Example 3

Efficacy screenhouse trials were conducted to evaluate the efficacy ofexperimental soybean events expressing both Cry proteins from aninsertion of a T-DNA segment from a single construct with two expressioncassettes (i.e., both Cry2Ab and Cry1A.105), or single Cry proteins(i.e., Cry2Ab only, or Cry1A.105 only) against artificial infestationsof lepidopteran pest populations contained in screenhouse enclosures.The comparison of single- to double-gene events was used to determinethe relative contribution of each single Cry protein towards theefficacy observed in the double-gene expression construct events. Thescreenhouse trials were conducted during multiple seasons in twogeographic locations. In one geographic location, 5 target pest specieswere tested: Anticarsia gemmatalis (velvetbean caterpillar, VBC),Chrysodeixis includens (soybean looper, SBL), Spodoptera eridania(southern armyworm, SAW), Spodoptera frugiperda (fall armyworm, FAW),and Helicoverpa zea (soybean podworm, SPW). In the second geographiclocation, 3 target pest species were tested: Crocidosema aporema (beanshoot moth, BSM), Rachiplusia nu (sunflower looper, SFL), and Spodopterafrugiperda (fall armyworm, FAW).

The events (i.e., entries) which were tested in these screenhouse trialswere generated from transformations with each of the separatetransformation constructs. Transformation events generated fromconstruct 1, 2, or 3, were evaluated in the R2 generation in screenhousetrials and included twenty events expressing both proteins (eventsgenerated from transformation with construct 1), six events expressingonly Cry2Ab (events generated from transformation with construct 2), andsix events expressing only Cry1A.105 (events generated fromtransformation with construct 3). Of these, 12 events with both Cry2Aband Cry1A.105 (construct 1), two events with Cry2Ab-only (construct 2),and three events with Cry1A.105-only (construct 3) were evaluated in theR3 generation in screenhouse trials. Eleven of the events with bothCry2Ab and Cry1A.105 (construct 1) were further evaluated in the R4generation screenhouse trials. Three events with both Cry2Ab andCry1A.105 (construct 1), one event with Cry2Ab-only (construct 2), andone event with Cry1A.105-only (construct 3) were evaluated in the R5,R6, and R7 screenhouse trials. Ten events expressing Cry2Ab andCry1A.105 (events generated from transformation with construct 4), threeCry2Ab-only events (events generated from transformation with construct5), and three Cry1A.105-only events (events generated fromtransformation with construct 6) were evaluated in the R3 generation toscreenhouse trials. Two events with both Cry2Ab and Cry1A.105, one eventwith Cry2Ab-only, and one event with Cry1A.105-only were evaluated inthe R4 screenhouse trials, and one event each was evaluated in the R5screenhouse trials. Three events expressing both Cry2Ab and Cry1A.105 inopposing 5′ to 3′ orientation with an enhancer (events generated fromtransformation with construct 8), 3 stacked events expressing bothCry2Ab and Cry1A.105 in opposing 5′ to 3′ orientation without anenhancer (events generated from transformation with construct 7), and 2Cry2Ab-only events (events generated from transformation with construct10) were evaluated in the R2 generation were evaluated in screenhousetrials. The positive transgenic soybean controls included MON87701 orevent GM_A19478 (generated at the same time as MON87701), and bothexpressing Cry1Ac. Non-transgenic soybean lines A3555 (parentalbackground for MON87751 events, relative maturity 3 (RM3)) and A5547(parental background for MON87701 and GM_A19478, RM5) were included inall screenhouse and field trials as negative controls. Thenon-transgenic soybean line AG3705 was included as a white flower checkin some trials.

Standard practices were followed in establishing and conducting thescreenhouse trials. The plots were evaluated once after each infestationat the time of maximal damage to the negative checks (usually 3-4 weeksafter pupae were placed within the screenhouse). At each evaluation, thefollowing agronomic observations were recorded: the date and the stageof plant growth. Additionally, for defoliating insects, an estimatedpercent defoliation in each plot was recorded. For C. aporema, tenplants were randomly selected in each plot and the number of plants withdamage was recorded. In some cases the numbers of live larvae were alsorecorded.

Defoliation data were subjected to ANOVA to determine significantsources of variability among line and replicate for each insect at eachlocation at the 0.05 probability level (P). Significant differencesamong means were determined using the Tukey-Kramer test (Kramer 1956) atP=0.05.

Three small-plot screenhouse trials were conducted in the secondgeographic location during one season using R. nu and C. aporema forinfestation. The trial design included Randomized Complete Block Design(RCBD) test blocks with three replicates per event or control, withevents tested shown in Table 4. One trial was infested with C. aporemaduring mid-vegetative stage of soybean growth and again at earlyreproductive stage of soybean growth. Two trials were infested with R.nu during mid-vegetative stage of soybean growth.

For the C. aporema trial, very heavy pressure was achieved. Replicatewas not a significant source of variability in damage (F=0.8794; df=2,69; P=0.4196), but event was highly significant (F=11.9398; df=23, 48;P<0.0001). The maximum percent of plants damaged (Table 4) averaged83-100% in the negative checks but was absent in the Cry1Ac positivecontrol. Events generated from transformation construct 1 and expressingCry2Ab and Cry1A.105 exhibited 0-13% of plants damaged, while thoseexpressing Cry2Ab-only or Cry1A.105-only exhibited 10-17% and 10-13%,respectively. The small, albeit significant, numbers of plants recordedas damaged in this trial may be due to the criteria used by theindividuals when recording the damage rating.

For the R. nu trials, heavy pressure was achieved in one screenhousetrial. Replicate was not a significant source of variability indefoliation (F=0.203; df=2, 69; P=0.8167), but event was highlysignificant (F=20.2461; df=23, 48; P<0.0001). Maximum defoliation (Table4) averaged 60-63% in the negative checks but was absent in the Cry1Acpositive control and events generated from transformation construct 1expressing Cry2Ab+Cry1A.105 or events generated from transformationconstruct 2 expressing Cry2Ab-only. Events generated from transformationconstruct 3 expressing Cry1A.105-only exhibited slightly higherdefoliation (4-10%). Moderately heavy pressure was achieved in thesecond screenhouse trial evaluating R. nu. Replicate was not asignificant source of variability in defoliation in either trial(F=0.2542; df=2, 69; P=0.7763), but event was highly significant(F=16.1793; df=23, 48; P<0.0001). Maximum defoliation (Table 4) averaged38-40% in the negative checks but was negligible in the Cry1Ac positivecontrol (4%) and absent in events generated with construct 1 andexpressing Cry2Ab+Cry1A.105 or events generated with construct 2 andexpressing Cry2Ab-only. Events generated with construct 3 and expressingCry1A.105-only exhibited slightly higher defoliation (2-7%).

In these screenhouse trials, soybean event MON87751 exhibited no damagedplants due to infestation of the insect pests, C. aporema or R. nu,which was significant compared to the damage and/or defoliation of thecontrols in the same trial (Table 4).

In a subsequent season of small-plot screenhouse trials conducted in thesecond geographic location, local lab populations of R. nu, C. aporemaand S. frugiperda were used for infestation. The protocols forconducting the trials were essentially as described above, and withevents and controls tested shown in Table 5.

For the trial infested with C. aporema, heavy pressure was achieved.Replicate was not a significant source of variability in damage(F=0.2742; df=2, 33; P=0.7619), but event was highly significant(F=8.2313; df=11, 24; P<0.0001). Maximum damage averaged 4.2-5.5 damagedpoints per plant in the negative checks, with 80-100% of plantsexhibiting damage, but was negligible in the positive control and alltest events (Table 5).

For the trial infested with R. nu, moderately heavy pressure wasachieved. Replicate was not a significant source of variability indamage (F=0.041; df=2, 33; P=0.9599), but event was highly significant(F=143.5526; df=11, 24; P<0.0001). Maximum damage averaged 33.3-40.0%defoliation in the negative checks (well above economic threshold) butwas absent or negligible in the positive control and all test eventsexcept the events generated by transformation with construct 6expressing only TIC105 (Table 5).

For the trial infested with S. frugiperda, light pressure was achieved.Replicate was not a significant source of variability in damage(F=0.1187; df=2, 33; P=0.8884), but event was highly significant(F=12.8602; df=11, 24; P<0.0001). Maximum damage averaged 7.5-15.0%defoliation in the negative checks—just reaching the economic threshold.Some damage was also noted in events expression only Cry2Ab generated bytransformation with either construct 2 or construct 5, but damage wasabsent or negligible in the positive control and all other test events(Table 5).

In these screenhouse trials, soybean event MON87751 exhibited no damagedplants due to infestation of the insect pests, C. aporema, R. nu, S.frugiperda, which was significant when compared to damage to thenegative controls in the same trial (Table 5). Soybean event MON87751had significantly less damage from R. nu when compared to transgenicsoybean events generated by transformation with construct 6 expressingonly Cry1A.105 (Table 5), though it is noted that there is lowerexpression of Cry1A.105 protein in the events generated bytransformation with construct 6. These results also demonstrate for thefirst time the expanded spectrum of control of the insect pest S.frugiperda.

One small-plot screenhouse trial was conducted in the first geographiclocation using infestation of a lab population of H. zea. The trialdesign included Randomized Complete Block Design (RCBD) test blocks withthree replicates per event, with events and controls tested shown inTable 6. There were two infestations of H. zea and defoliation wasassessed 19-27 days post-infest (R2-R3 stage of soybean growth) for thefirst infestation, and 25-28 days post-infest (R5 stage of soybeangrowth) for the second infestation. The results from the screenhousetrials testing the insect pest, H. zea, are as follows: moderately heavypressure was achieved. Replicate was not a significant source ofvariability in defoliation (F=0.326; df=2, 105; P=0.7225), but event washighly significant (F=13.8864; df=35, 72; P<0.0001). Maximum defoliation(Table 6) averaged 32-33% in the negative checks but was negligible inthe Cry1 Ac positive control (1%) and events generated with construct 1and expressing Cry2Ab+Cry1A.105 (2-4%). A somewhat higher defoliationwas observed in events generated with construct 4 expressingCry2Ab+Cry1A.105 (5-12%), events generated with construct 5 expressingonly Cry2Ab (13-17%) or events generated with construct 6 expressingonly Cry1A.105 (8-12%).

Soybean event MON87751 exhibited significantly less damage by H. zea inthis screenhouse trial when compared to damage to the negative controlsin the same trial. This level of control by H. zea is within acceptablecommercial level of control for this soybean pest species. Additionally,in this screenhouse trial, soybean event MON87751 had significantly lessdamage when compared to transgenic soybean events generated withconstruct 5 expressing only Cry2Ab (Table 6), demonstrating expandedlevel of control. However, expression of Cry2Ab is lower in eventsgenerated with construct 5 than in events generated with construct 2,and the significant defoliation of events generated with construct 5expressing only Cry2Ab may indicate that there may be reduced efficacyagainst H. zea by Cry2Ab in generated with construct 5.

The results for these screenhouse trials show that soybean eventMON87751 exhibited significantly less damage by S. eridania(1^(st)-instar or 3^(rd)-instar), A. gemmatalis (1st_ instar), or C.includens (1st-instar) when compared to damage to the negative controlsin the same trial (Table 7 and Table 8). Additionally, in thesescreenhouse trials, soybean event MON87751 had significantly less damageby S. eridania (1^(st)-instar and 3rd-instar) larvae when compared totransgenic soybean events expressing Cry1Ac (Table 7 and Table 8),demonstrating the expanded performance of event MON87751 to transgenicsoybean event currently available for lepidopteran pest control.Further, in these screenhouse trials, soybean event MON87751 hadsignificantly less damage by S. eridania larvae when compared to [1] anyof the events generated with constructs 4, 5, or 6 (3^(rd)-instarlarvae), or events generated with construct 6 expressing only Cry1A.105event (1^(st) instar larvae), or events generated with construct 3expressing only Cry1A.105 event (1^(st) instar larvae and 3^(rd)-instarlarvae) and [2] when compared to events generated with construct 7expressing Cry2Ab and Cry1A.105 without an enhancer (1^(st) instar- and3^(rd)-instar larvae), demonstrating the superior performance of theevent MON87751 to the events generated with constructs 4, 5, 6, or 7(Table 7 and Table 8).

Example 4

Open field efficacy trials were conducted to evaluate the efficacy ofexperimental soybean event MON87751 and events created using thedifferent transformation constructs 1, 2, 3, 4, 5, and 6, againstnatural field infestations of lepidopteran pest populations. Thecomparison of events generated with construct 2 or 5 (expression ofCry2Ab only), and events generated with construct 3 or 6 (expression ofCry1A.105 only), to events generated with construct 1 or 4 (expressionof both Cry1Ab and Cry1A.105) was used to determine the relativecontribution of each single Cry protein (i.e. Cry2Ab only, or Cry1A.105only) towards the efficacy observed in events expressing both Cryproteins (i.e., Cry2Ab and Cry1A.105) from a single construct. Theefficacy field trials of native populations of endemic soybean pestswere conducted over multiple seasons, at multiple field trial sites, andin three geographic locations.

In the initial efficacy field trials conducted in one geographiclocation, the events (i.e., entries) evaluated included twelve eventsgenerated by construct 1 and expressing both Cry proteins, Cry2Ab andCry1A.105 (and including event MON87751), two events generated byconstruct 2 and expressing only Cry2Ab, and three events generated byconstruct 3 expressing only Cry1A.105. In the initial efficacy fieldtrials conducted in a second geographic location, the events generatedby constructs 1, 2 and 3 were evaluated and included 11 eventsexpressing both Cry proteins, Cry2Ab and Cry1A.105 (generated fromtransformation with construct 1 and including event MON87751), twoevents expressing only Cry2Ab (events generated from transformation withconstruct 2), and three events expressing only Cry1A.105 (eventsgenerated from transformation with construct 3). In a second season ofefficacy field trials conducted in 3 geographic locations, the events(i.e., entries) evaluated included three events expressing both Cryproteins, Cry2Ab and Cry1A.105 (events generated from transformationwith construct 1 and including event MON87751), one event expressingonly Cry2Ab (events generated from transformation with construct 2), andone event expressing only Cry1A.105 (events generated fromtransformation with construct 3). The events evaluated in the open fieldefficacy trials included generations R3 through R7.

For each efficacy field trial site, test blocks were planted and naturalinfestation by native pest populations of the target lepidopteraninsects was allowed to occur. The test block remained untreated withinsecticides for the target pests (Lepidoptera). However, the testblocks may have been sprayed to prevent significant damage by non-targetinsect pests. All experimental events were in the soybean germplasmbackground A3555, of relative maturity group 3 (RM3). The other entriesin the trials included the positive control MON87701 (expressing Cry1Ac)or GM_A19459 (RM5); the negative parental check A3555 (purple flower,RM3); and the negative commercial check A5547 (white flower, MG5) orCMA5805 (white flower, RM5).

Standard practices were followed in establishing and conducting the openfield efficacy trials. Larval incidence of lepidopteran pests,defoliation, and plant growth stage were recorded periodically (i.e.,every 5-14 days) commencing with onset of target lepidopteran activityand ending when target lepidopteran activity ceased or plants reached R7stage of growth. Pest incidence data was collected from rows 1 and 4only to avoid plant damage in rows 2 and 3, which were harvested foryield data. Monitoring and recording of pest incidence data occurred asfollows: defoliating lepidopterans (i.e., A. gemmatalis, C. includens,R. nu, Spodoptera spp.) were monitored using a drop cloth or verticalbeating sheet, with at least two drop cloth or four vertical beatingsheet samplings per plot. The total number of larvae for each targetspecies encountered and the number of samplings within each plot wererecorded as the mean number of larvae per m row (total numberlarvae÷number samplings÷cloth/sheet length in meters) for each targetspecies encountered. Subsequent samplings were done in a manner whichavoided repeated sampling in the same area of each plot. In the efficacyfield trials conducted at one geographic location, data were alsorecorded at two trial sites for opportunistically for damage by H. zeaby randomly selecting 20 or 33 plants/location, and recording the numberwith larval feeding damage. At a second geographic location, one trialwas rated opportunistically for H. zea by randomly selecting 10 plantsper plot and recording total number of pods and number of damaged podsper plant.

Data for infestation by Elasmopalpus lignosellus were recorded bycounting the total number of plants in each plot with damage (wilted,dying, or dead) due to larval feeding. Damage data for this insect wastaken at a single time point when maximal damage was noted.

In addition to target pests, non-targets pests, primarily those withpotential for surpassing economic thresholds (e.g., stink bugs), weremonitored periodically by sweep net, modified sweep net, or ground clothat randomly selected locations within the test block, and assessed todetermine whether they reached or were approaching economic injurylevels

At trial maturity, the entire length of rows 2 and 3 of each plot wereharvested, and both total weight and percent moisture for each plot wasrecorded. During harvest, significant gaps (plants not touching eachother) in harvested rows were noted and the total length of these gapswas recorded. Yields were calculated after correcting seed weight to 13%moisture. Larval incidence, defoliation, and yield data were subjectedto ANOVA to determine significant sources of variability among line andreplicate for each location at the 0.05 probability level (P).Significant differences among means were determined using theTukey-Kramer test (Kramer 1956) at P=0.05.

In open field trials conducted at field trial site 1, defoliatingcaterpillars were first encountered at the R3 stage of growth, andincreased to moderately damaging levels by the R6 stage of growth.Species encountered included A. gemmatalis (98%), R. nu (2%) andSpodoptera spp. (1%). Replicate was not a significant source ofvariability in larval incidence (F=0.0435; df=2, 57; P=0.9575),defoliation (F=0.0807; df=2, 57; P=0.9226) or yield (F=0.0213; df=2, 57;P=0.979), but event was highly significant for all three (larvalincidence: F=69.6956; df=19, 38; P<0.0001; defoliation: F=25.9918;df=19, 40; P<0.0001; yield: F=3.357; df=19, 38; P=0.0007). Cumulativelarval incidence (Table 9) reached 139-189 larvae per m row in thenegative checks, while virtually no larvae were encountered in any ofthe transgenic entries. Maximum defoliation (Table 9) averaged 21-27% inthe negative checks and was absent in all transgenic entries. Yields(Table 9) were reduced in both negative checks relative to alltransgenic entries, although variability in yield reduced thesignificance of these reductions.

Event MON87751 had a significantly lower incidence of defoliatinglepidopteran larvae (season cumulative) and significantly lower percentdefoliation (season maximum) when compared to non-transgenic controls.

At another open field trial, conducted at field trial site 2,defoliating caterpillars were first encountered at the late vegetativestage of growth, and increased to highly damaging levels by the R3 stageof growth. Species encountered included A. gemmatalis (53%), “loopers”(probably C. includens, but R. nu possible) (44%) and Spodoptera spp.(3%). Replicate was not a significant source of variability in larvalincidence (F=0.0085; df=2, 57; P=0.9915) or defoliation (F=0.0027; df=2,57; P=0.9973), while event was highly significant for both (larvalincidence: F=19.644; df=19, 40; P<0.0001; defoliation: F=671.3147;df=19, 40; P<0.0001). Cumulative larval incidence (Table 10) reached43-50 larvae per m row in the negative checks, while negligible numberswere encountered in the transgenic entries. Maximum defoliation (Table10) averaged 87-90% in the negative checks, while no more than tracelevels were observed in all transgenic entries.

Event MON87751 had a significantly lower incidence of incidence ofdefoliating lepidopteran larvae (season cumulative), and a significantlylower percent defoliation (season maximum), when compared tonon-transgenic controls.

The reduced number of pods per plant in the negativechecks is likely a result of premature pod abscission caused by podwormdamage, as numerous damaged pods were observed lying on the groundbeneath the plants in the negative checks (but not the test events)(Table 11).

At another open field trial, conducted at field trial site 6,defoliating caterpillars (primarily H. zea and C. includens) wereencountered during the R6 stages of growth but never reached highlysignificant numbers. However, substantial damage to plants by E.lignosellus in borders, buffers, and negative checks occurred earlier inthe season, resulting in wilted, dying, and dead plants by the R5-R6stage of growth, at which time damage data were recorded. Replicate wasnot a significant source of plants damaged by E. lignosellus (F=0.3431;df=2, 69; P=0.71). Event was highly significant for plants damaged by E.lignosellus: F=16.7555; df=23, 48; P<0.0001). The percent of plantsdamaged by E. lignosellus (Table 14) averaged 10-28% in the negativechecks, while no plants in any of the transgenic entries exhibiteddamage, including event MON87751.

At another open field trial, conducted at field trial site 7,defoliating caterpillars were first encountered at the R1-R2 stage ofgrowth and increased to highly damaging levels by the R4-R6 stage ofgrowth. Species encountered included C. includens (54%), Spodopteraexigua (43%), and Estigmene acrea (2%). Replicate was not a significantsource of variability in larval incidence (F=0.0866; df=2, 69;P=0.9172), or defoliation (F=0.1129; df=2, 69; P=0.8934).

Cumulativelarval incidence (Table 15) reached 152-166 larvae per m row in thenegative checks, while virtually no larvae were encountered in theCry1Ac positive control, or events generated with constructs 1, 2, or 3expressing Cry2Ab and/or Cry1A.105. Maximum defoliation (Table 15)averaged 24% in the negative checks but did not exceed trace levels inevents generated with constructs 1, 2, or 3 expressing Cry2Ab and/orCry1A.105, including event MON87751 or the Cry1Ac positive control.

At another open field trial, conducted at field trial site 8, moderatepressure by the defoliating caterpillars C. includens (41%), A.gemmatalis (38%), S. frugiperda (13%) and S. ornithogalli (8%) occurredduring the R4-R6 stages of growth. Replicate was not a significantsource of variability in larval incidence (F=0.0924; df=3, 52;P=0.9639), or defoliation (F=0.372; df=3, 52; P=0.7735).

During a second season of open field trials conducted at field trialsite 6, very heavy pressure by H. zea occurred during the R3-R5 stagesof growth.

The results of the multiple open field trials described in this example,combined with the results of the multiple screenhouse trials (describedin Example 3) further confirm effective, season-long suppression oflarval populations of all lepidopteran soybean pests encountered bytransgenic soybean events generated by constructs 1, 2 or 3 across fiveplant generations (R2 through R7), suggesting stable transgeneexpression within and across generations.

The combined results demonstrate that, under conditions ofabove-threshold pressure by all four primary target pests (Anticarsiagemmatalis and Chrysodeixis includens in one geographic location, andthe same target pests plus Rachiplusia nu and Crocidosema aporema in asecond geographic location), efficacy by transgenic events generatedwith constructs 1, 2 or 3, including event MON87751, was equivalent to atransgenic event expressing Cry1Ac and previously demonstrated tocontrol lepidopteran insect pests of soybean. The events generated withconstructs 2 or 3 and expressing only Cry2Ab protein or only Cry1A.105protein, respectively, also demonstrated equivalent efficacy to thetransgenic event expressing Cry1Ac protein, suggesting that expressionof both Cry2Ab and Cry1A.105 proteins in event MON87751 will haveimproved durability over the Cry1Ac transgenic event through improvedinsect resistance management.

Equivalent efficacy among the events generated with construct 1,including event MON87751, has also been demonstrated against numeroussecondary target pests, including three species of armyworm (Spodopteraexigua, S. frugiperda and S. eridania), two heliothine podworms(Helicoverpa zea and H. gelotopeon), one stalkboring insect(Elasmopalpus lignosellus) and one defoliator (Plathypena scabra).

Example 5

This example describes the molecular characterization of event MON87751,which included protein expression and extensive molecularcharacterization. This molecular characterization was completedconcurrently on events which were being tested in agronomic fieldtrials, efficacy screenhouse trials, and efficacy field trials.

For molecular characterization of event MON87751, copy number of thetransgene insert sequence (comprising both Cry2Ab and Cry1A.105cassettes, SEQ ID NO:9) was determined using a combination of Southernanalysis and endpoint TAQMAN® assay. The molecular analysis confirmedthat there was only a single insert (T-DNA expression cassettecontaining expression cassettes for both Cry2Ab and Cry1A.105 proteins,and represented by SEQ ID NO:9) with no detection of the vectorbackbone, and no detection of the T-DNA cassette containing theselection/scorable marker sequences. The full sequence of the singleinsert (SEQ ID NO:9) in event MON87751 genomic DNA confirmed that thesequence was identical to the sequence of the transformation construct.

For protein expression, leaf samples were collected from plantshomozygous for event MON87751 allele and extracts prepared fromlyophilized samples, ELISAs were conducted per standard protocolsmeasuring protein level of Cry2Ab or Cry1A.105 with antibodies specificfor Cry2Ab or Cry1A.105, respectively, and results were expressed asparts per million (ppm) of dry weight. Leaf samples were collected atthe R1 and R3 stage of plant growth for events generated bytransformation with constructs 1, 2 or 3 and the non-transgenic controlA3555. ELISA results indicated that Cry2Ab levels for events generatedfrom construct 1 and construct 2 ranged from about 20 ppm to about 50ppm dry weight, with the exception of event 8 (which was determined tohave a linked viral promoter, but no other sequence, from theselectable/scorable marker T-DNA, and event 8 was not furtherevaluated), and no Cry2Ab expression from the events generated withconstruct 3 (expressing Cry1A.105 only) or the non-transgenic control(FIG. 3A). Further the Cry2Ab protein expression levels wereapproximately equal for both R1 and R3 growth stages. ELISA resultsindicated that Cry1A.105 levels for events generated from construct 1and construct 3 ranged from about 150 ppm to about 800 ppm dry weight,and no Cry1A.105 expression from either the events generated withconstruct 2 (expressing Cry2Ab only) or the non-transgenic control (FIG.3B). Further the Cry1A.105 protein expression levels ranged higher forleaf samples at the R3 growth stage compared to the R1 growth stage.

Additional ELISA results show that Cry2Ab protein levels from eventsgenerated with construct 1 were higher relative to events generated witheither construct 5 or construct 4, and as expected, there was no Cry2Abdetected for either the non-transgenic control or the events generatedwith construct 6 (expressing Cry1A.105 only) (FIG. 4A). In the same setof leaf samples, ELISA results show that there is a two-fold or higherlevel of expression of Cry1A.105, for events generated with construct 1,with an approximate four-fold higher expression for MON87751, whencompared to events generated with either construct 6 or construct 4, andas expected, there was no Cry1A.105 expression detected for either thenon-transgenic control or the events generated with construct 5(expressing Cry2Ab only) (FIG. 4B). For these ELISAs, leaf samples werecollected from the R3 stage of growth from plants grown at each of twoseparate efficacy screenhouse trial locations.

Further ELISA results show that Cry2Ab protein levels in extracts froman event generated with construct 1, and an event generated withconstruct 2 were a) higher relative to events generated with eitherconstruct 4, construct 5, or construct 7; b) approximately the same orsomewhat lower relative to events generated with either construct 9, orconstruct 11; and c) as expected, there was no Cry2Ab detected foreither the non-transgenic control (not shown) or the events generatedwith either construct 3 or construct 6 (expressing Cry1A.105 only) (FIG.5). For these ELISAs, leaf samples were collected at the R3 and R5 stageof growth, and the Cry2Ab levels were higher at the R5 growth stage forevents generated with construct 1 and construct 2, and the Cry2Ab levelswere higher in events generated with construct 9, and construct 11 (FIG.5). In the same set of leaf samples, ELISA results show that Cry1A.105protein levels in extracts from events generated with construct 1 andconstruct 3 were significantly higher relative to events generated withconstruct 4, construct 6, construct 9 or construct 7, and, as expected,there was no Cry1A.105 detected for either the non-transgenic control(not shown) or the events generated with either construct 2 or construct5 (expressing Cry2Ab only) (FIG. 6). For these ELISAs, leaf samples werecollected at the R3 and R5 stage of growth, and the Cry1A.105 levelswere orders of magnitude higher at the R5 growth stage for eventsgenerated with construct 1 and construct 3, compared to events generatedwith construct 4, construct 6, construct 9 or construct 7, see FIG. 6AY-axis plotted at 0-5000 ppm dry weight and FIG. 6B Y-axis plotted at0-500 ppm dry weight. The ELISA data indicate that there is higherexpression of both Cry2Ab and Cry1A.105 in events generated withconstruct 1 compared to events generated with construct 4, construct 7or construct 9, all containing two Cry protein expression cassettes—oneexpression cassette encoding Cry2Ab and one expression cassette encodingCry1A.105. Additionally, it was noted that the relatively high proteinexpression in events generated with construct 1 (including eventMON87751), construct 2, and construct 3, was stable over at least 4generations of soybean (R0, R1, R2, and R3), and the Cry1A.105 proteinlevel increased in leaf tissue collected from homozygous events at theR3 to R5 stage of growth.

Example 6

This example describes methods useful in identifying the presence ofevent MON87751 DNA in a soybean sample. A pair of PCR primers and aprobe were designed for the purpose of identifying the unique junctionformed between the genomic DNA and the arbitrarily assigned 3′ end ofthe inserted DNA of event MON87751 (i.e., the 3′ junction) andencompassed in SEQ ID NO:10, SEQ ID NO: 8, SEQ ID NO:2, SEQ ID NO:4, orSEQ ID NO:6.

The sequence of the oligonucleotide forward primer SQ20267 (SEQ IDNO:11) is identical to the nucleotide sequence corresponding topositions 11400 through 11426 of SEQ ID NO:10, and positions 212 through238 of SEQ ID NO:8, and positions 10066 through 10092 of SEQ ID NO:9.The sequence of the oligonucleotide reverse primer SQ25826 (SEQ IDNO:12) is identical to the reverse compliment of the nucleotide sequencecorresponding to positions 11454 through 11479 of SEQ ID NO:10, andpositions 266 through 291 of SEQ ID NO:8, and positions 51 through 76 ofSEQ ID NO:6, and positions 31 through 56 of SEQ ID NO:4. The sequence ofthe oligonucleotide probe PB10263 (SEQ ID NO:13) is identical to thenucleotide sequence corresponding to positions 11428 through 11446 ofSEQ ID NO:10, and positions 10094 through 10112 of SEQ ID NO:9, andpositions 240 through 258 of SEQ ID NO:8, and positions 25 through 43 ofSEQ ID NO:6, and positions 5 through 23 of SEQ ID NO:4. The PCR primersSQ20267 (SEQ ID NO:11) and SQ25826 (SEQ ID NO:12) amplify an 80nucleotide amplicon of the unique the genomic/insert DNA at the rightjunction of event MON87751. This same primer pair with probe PB10263(SEQ ID NO:13), which may be fluorescently labeled (e.g., a 6FAM™fluorescent label), can be used in an Endpoint TaqMan® PCR assay toidentify the presence of DNA derived from event MON87751 in a sample.

In addition to SQ20267 (SEQ ID NO:11), SQ25826 (SEQ ID NO:12) andPB10263 (SEQ ID NO:13), it should be apparent to persons skilled in theart that other primers and/or probes can be designed to either amplifyand/or hybridize to sequences within SEQ ID NO:10 which are unique to,and useful for, detecting the presence of DNA derived from eventMON87751 in a sample.

Following standard molecular biology laboratory practices, PCR assaysfor event identification were developed for detection event MON87751 DNAin a sample. Parameters of either a standard PCR assay or a TaqMan® PCRassay were optimized with each set of primer pairs and probes (i.e.probes labeled with a fluorescent tag such as 6FAM™) used to detect thepresence of DNA derived from event MON87751 in a sample SQ20267 (SEQ IDNO:11), SQ25826 (SEQ ID NO:12) and PB10263 (SEQ ID NO:13). A control forthe PCR reaction includes internal control primers and an internalcontrol probe (e.g., VIC™-labeled), specific to a single copy gene inthe soybean genome. One of skill in the art will know how to designprimers specific to a single copy gene in the soybean genome. Generally,the parameters which were optimized for detection of event MON87751 DNAin a sample included primer and probe concentration, amount of templateDNA, and PCR amplification cycling parameters. The template DNA samplesand controls were as follows: [1] DNA extracted from either leaf sampleor single seed sample to be analyzed; [2] negative control DNA(non-transgenic soybean DNA); [3] negative water control (no template);and [4] positive control MON87751 DNA. Other methods known to thoseskilled in the art that produce amplicons that identify the eventMON87751 DNA in a sample is within the skill of the art.

A zygosity assay is useful for determining if a plant comprising anevent is homozygous for the event DNA; that is comprising the exogenousDNA in the same location on each chromosome of a chromosomal pair; orheterozygous for an event DNA, that is comprising the exogenous DNA ononly one chromosome of a chromosomal pair; or is null for the event DNA,that is wild-type. An endpoint TAQMAN® thermal amplification method wasused to develop a zygosity assay for event MON87751. For this assay,three primers and two probes were mixed together with the sample for theassay. The three primers were SQ20267 (SEQ ID NO:11), which hybridizesand extends specifically from the 3′ region of the inserted exogenousDNA; primer SQ27115 (SEQ ID NO:14), which hybridizes and extendsspecifically from the soybean genomic DNA flanking the 3′ side of theinserted exogenous DNA; and primer SQ26901 (SEQ ID NO:15), whichhybridizes and extends specifically from the soybean genomic DNAflanking the 5′ side of the inserted exogenous DNA. Primers SQ20267 andSQ27115 and the probe PB 10263 (SEQ ID NO:13) (6-FAM™-labeled) arediagnostic when there is a copy of the inserted exogenous DNA present inthe template DNA, i.e., for event MON87751. Primers SQ26901 and SQ27115and the probe PB11254 (SEQ ID NO:16) (VIC™-labeled) are diagnostic whenthere is no copy of the inserted exogenous DNA present in the genomicDNA, i.e. wild-type. When the three primers and two probes are mixedtogether in a PCR reaction with DNA extracted from a plant homozygousfor event MON87751, there is a fluorescent signal only from6-FAM™-labeled probe PB 10263 which is indicative of and diagnostic fora plant homozygous for event MON87751. When the three primers and twoprobes are mixed together in a PCR reaction with DNA extracted from aplant heterozygous for event MON87751, there is a fluorescent signalfrom both the 6-FAM™-labeled probe PB 10263 and the VIC™-labeled probePB 11254 which is indicative of and diagnostic for a plant heterozygousfor event MON87751. When the three primers and two probes are mixedtogether in a PCR reaction with DNA extracted from a plant which is nullfor event MON87751 (i.e. wild-type), there is a fluorescent signal fromonly the VIC™-labeled probe PB11254 which is indicative of anddiagnostic for a plant null for event MON87751, i.e. wild-type. Thetemplate DNA samples and controls were as follows: [1] DNA extractedfrom either leaf sample or single seed sample to be analyzed; [2]negative control DNA (non-transgenic DNA); [3] negative water control(no template); [4] positive control MON87751 genomic DNA from knownheterozygous sample; and [5] positive control MON87751 genomic DNA fromknown homozygous sample.

Example 7

The following example describes how one may identify the MON87751 eventwithin progeny of any breeding activity using soybean event MON87751.

DNA event primer pairs are used to produce a PCR amplicon diagnostic forsoybean event MON87751. An amplicon diagnostic for MON87751 comprises atleast one junction sequence, provided as SEQ ID NO:1 or SEQ ID NO:2 orSEQ ID NO:3 or SEQ ID NO:4 or SEQ ID NO:5 or SEQ ID NO:6. Primer pairsthat will produce a diagnostic amplicon for MON87751 include primerpairs based upon the flanking sequences and the inserted expressioncassette (SEQ ID NO:9). To acquire a diagnostic amplicon in which SEQ IDNO:1 or SEQ ID NO:3 or SEQ ID NO:5 is found, one would design a forwardprimer molecule based upon SEQ ID NO:7 from bases 1 through 1334 and areverse primer molecule based upon the inserted expression cassette DNAsequence (SEQ ID NO:9 from positions 1 through 10119) in which theprimer molecules are of sufficient length of contiguous nucleotides tospecifically hybridize to SEQ ID NO:7 and SEQ ID NO:9. To acquire adiagnostic amplicon in which SEQ ID NO:2 or SEQ ID NO:4 or SEQ ID NO:6is found, one would design a forward primer molecule based upon theinserted expression cassette DNA sequence (SEQ ID NO:9 from positions 1through 10119) and a reverse primer molecule based upon the 3′ flankingsequence (SEQ ID NO:8 from position 266 through 1452), in which theprimer molecules are of sufficient length of contiguous nucleotides tospecifically hybridize to SEQ ID NO:8 and SEQ ID NO:9.

An example of the amplification conditions for this analysis isillustrated in Example 4. However, any modification of these methods orthe use of DNA primers homologous or complementary to SEQ ID NO:7 or SEQID NO:8 or DNA sequences of the genetic elements contained in thetransgene insert (SEQ ID NO:9) of MON87751 that produce an amplicondiagnostic for MON87751 is within the art. A diagnostic ampliconcomprises a DNA molecule homologous or complementary to at least onetransgene/genomic junction DNA (SEQ ID NO:1 or SEQ ID NO:2 or SEQ IDNO:3 or SEQ ID NO:4 or SEQ ID NO:5 or SEQ ID NO:6), or a substantialportion thereof. Alternatively, a diagnostic amplicon comprises a DNAmolecule homologous or complementary to at least one unique transgenesequence (SEQ ID NO:17 or SEQ ID NO:18 or SEQ ID NO:19 or SEQ ID NO:20or SEQ ID NO:21 or SEQ ID NO:22 or SEQ ID NO:23).

An analysis for event MON87751 plant tissue sample should include apositive tissue control from event MON87751, a negative control from asoybean plant that is not event MON87751 (for example, but not limitedto A3555), and a negative control that contains no soybean genomic DNA.A primer pair that will amplify an endogenous soybean DNA molecule willserve as an internal control for the DNA amplification conditions.Additional primer sequences can be selected from SEQ ID NO:7, SEQ IDNO:8, or SEQ ID NO:9 by those skilled in the art of DNA amplificationmethods, and conditions selected for the production of an amplicon bythe methods shown in Example 4 may differ, but result in an amplicondiagnostic for event MON87751 DNA. The use of these DNA primer sequenceswith modifications to the methods of Example 4 are within the scope ofthe invention. The amplicon produced by at least one DNA primer sequencederived from SEQ ID NO:7, SEQ ID NO:8, or SEQ ID NO:9 that is diagnosticfor MON87751 is an aspect of the invention.

DNA detection kits contain at least one DNA primer of sufficient lengthof contiguous nucleotides derived from SEQ ID NO:7, SEQ ID NO:8, or SEQID NO:9, that when used in a DNA amplification method produces adiagnostic amplicon for MON87751 or its progeny is an aspect of theinvention. A MON87751 soybean plant, plant part, plant cell, seed, orcommodity product that will produce an amplicon diagnostic for MON87751when tested in a DNA amplification method is an aspect of the invention.The assay for the MON87751 amplicon can be performed by using an AppliedBiosystems GeneAmp® PCR System 9700 (run at maximum speed) or MJResearch DNA Engine PTC-225 thermal cycler or any other amplificationsystem that can be used to produce an amplicon diagnostic of MON87751 asshown in Example 4.

Example 8

To produce soybean plants or plant parts thereof which comprise enhancedagronomic, insecticidal, or herbicidal properties, soybean plantscontaining event MON87751 are crossed with soybean plants containingpotentially any other soybean event or combination thereof andphenotypes are evaluated to determine the resulting properties of theprogeny plants. Properties conferred to progeny plants resulting fromsuch plant breeding can extend beyond lepidopteran resistance of eventMON87751, including, but not limited to above-ground pest control,herbicide tolerance, nematicidal properties, drought resistance, virusresistance, anti-fungal control, bacteria resistance, male sterility,cold tolerance, salt tolerance, increased yield, enhanced oilcomposition, increased oil content, enhanced nutrient use efficiency, oraltered amino acid content.
